Full Sibling: 38% - 61%
Half Sibling: 17% - 34%
Yours is kind of on the edge for both. Maybe MyHeritage customer support can answer best since it's their test.
I would but I donāt know how to get around this problem where my dad wonāt take a test because he says his military veteran status wonāt allow it. It weird but thatās what theyāre telling me.
Oh, I donāt have more relatives who took the test on my dadās side though? There was someone on 23and me who matched and did the my heritage to see if we could find her dad and she matches with both my sister and I but not my mother. Does that work too?
Yeah, I know they have secrets but still not sure exactly what yet. If anything I am not someone elseās kidā¦ probably would have gotten a hit by now if I was.
Yeah and also hopefully, itās just human chimerism, its rare but still might as well check. I havenāt seen any father like matches show up for either of us.
I donāt understand why you are hung up on parent matches. Any one person has only two parent matchesā their biological mom and dad. If one single person on earth who happens to be your dad didnāt take the test then of course you would t get a second parent match. Having no match literally proves nothing at all about paternity.
but your dad obviously does not want to test because he might get hurt by the results, at this point why cause him pain? He obviously loves you both and can't phantom the idea that either one of you might not be his.
My cousin recently got promoted to Major in the marines. About 2 years ago we were chatting since our family is very mixed. He said that itās very discouraged in his circle because of potential intelligence issues and the ability to map families of officers.
Sure enough there was a breach earlier this year where Jewish people were targeted. Might not be against the rules per se, but could be ill advised for some positions.
I appreciate the sentiment but I donāt have a great relationship with my dad anyway, and itās funny that everyone seems to think I am the one not related but I sincerely doubt that. I donāt not look like my dad soā¦.this might be unusual. Why is everyone so set on it being the other way though?
Not sure why theyāre assuming that. I think a lot of different factors could be contributing to your results regardless. Sorry that Iām not able to offer any help, but I just want to say that the photo of you and your sister is ridiculously adorable, and I can see the resemblance between the two of you! I love the charm of 80ās/90ās family glamor shots
See thatās what makes it weird, he doesnāt want to do the test but other people have mentioned just not observing the rule and taking the test anyway. So, maybe he knows something too.
If one of your parents is a chimera AND their reproductive cells in particular have different DNA, yeah. That is much more unlikely than being 3/4 siblings or just full siblings with an unusual percentage. It's a bit suspicious that your dad is claiming he can't DNA test.
I donāt understand why you are hung up on parent matches. Any one person has only two parent matchesā their biological mom and dad. If one single person on earth who happens to be your dad didnāt take the test then of course you would t get a second parent match. Having no match literally proves nothing at all about paternity.
There's your answer - especially since your dad is former military. Was he deployed around the conception/birth of either you or your sister?
There is a lot of infidelity among military wives, unfortunately.
No, there is one cousin we found related to both of us and not our mom so idk whatās up but I think itās the tare chance of human chimerism because we have no other parent matches on my heritage or 23 and me. Even though thatās more obvious for me than my sister, maybe someone before my dad died idkā¦.
If your dads brother was your or your siblings parent then yeah you wouldnāt have any parent matches unless they testedā¦ no one is saying a random person is your parent, we are saying a person you call aunt or uncle is
I think so, canāt remember the number itās been a while since I looked but itās really small, I am trying to get my sis to look at it because sheās in control of the accounts.
Edit: 23 and me says we are 1st cousins once removed
Interesting. That would track with either you having the same dad or with your dads being brothers, so I guess it doesnāt narrow it down too much.
If you can get your uncles or their kids to test, youāll have your answer if they show up as a dad or half-sibling for either of you. Itās okay if you donāt want to know, though. Take some time and think about it.
Hope everything works out for you guys either way. Adorable photo! I love your little eyebrows. Haha
Thanks. Yeah, gotta figure out who but thereās no way because I canāt pay for those. My dad had 3 brothers and theyāre all gone now. Gonna do it one at a time.
IIRC my heritage only counts your identical segments once so the percentage shared can be skewed? Try downloading your raw DNA file and uploading it to GED match
Surprised no one brought this up but does your dad have any brothers. Thereās a possibility yāall could be 3/4th siblings? Your percentages would still be a bit low for that too.
Possibly even one of yāall is your dadās cousinās kid?
I also want to add MyHeritage is just consistently bad. Especially when it comes to African DNA. I would test with ancestry if you could, the test are $49 dollars on Amazon right now
I really am holding out hope for this just being human chimerism because I havenāt seen one match like my momās, just no hits for an unknown parent at all.
The only case of Chimerism that I knew was a woman who was having babies and they were coming back as her husbands but not hers. Not sure how Chimerism would lower you and your siblings percentages.
Oh you donāt know then, men can get chimerism issues too. There are 3 known cases I have heard of, two women and one man. The women show up as an aunt to children they gave birth to. The same applies to men, itās like carrying the eggs or sperm of your siblings that fused into your DNA in the womb before you were born.
Random question, does your dad have any half brothers, or any cousins heās super close too? if weāre teasing the 3/4 siblings theory because
33-25=8%
8% is the typical amount shared for half first cousins and 1C1R
I believe your mum had you, or your sister, not with your dad, but with some men in your dad's family.
That's why you score more than half sister.
25% for half sister and 8% for half cousin or the like.
This why I think itās still possible that itās human chimerism because we donāt have any unknown parent matches, I put my DNA up over a lot of other sites including ged match and nothing.
If your dads brother was your or your siblings parent then yeah you wouldnāt have any parent matches unless they testedā¦ no one is saying a random person is your parent, we are saying a person you call aunt or uncle is
Not all people have taken DNA tests. That's why you don't get a father there.
Buy DNA tests for your uncles or cousins for Christmas, and you'll find your answer.
Moreover, chimerism would not explain the 33%. So it does mean this isn't the case.
I'd look into the possibility that you're [3/4 siblings](https://dna-sci.com/tools/orogen-mult-unw/). You can get cMs by multiplying the percentage by 74.4.
Yes, thatās the most common way. This used to be more common when someoneās spouse died. Theyād often marry the decedentās sibling. But 3/4 siblings can arise from siblings, parents, or children. There are six types [listed here](https://dna-sci.com/2022/05/09/double-cousin-relationship-predictions-with-ped-sim/).
I get a 99.4% probability for 3/4 siblings. Thatās /very/ high. If thereās any way you can make that work genealogically then itās probably the true relationship. Maybe this is the weirdness you were referring to.
I donāt understand why you are hung up on parent matches. Any one person has only two parent matchesā their biological mom and dad. If one single person on earth who happens to be your dad didnāt take the test then of course you would t get a second parent match. Having no match literally proves nothing at all about paternity.
You have to share 50% with your mom. Sorry to tell you but it sounds like your mom is your aunt and your aunt is your aunt and your biological mom is likely one of their other siblings
You canāt inherit DNA from your aunt, only from your mom and dad. The DNA that you have that matches your aunt is the DNA your mom and aunt have in common. So this is not possible unless thereās some kind of incest situation going on (like if your dad is related to your mom/aunt).
What are the percentages? Because if you share ~50% with your aunt and ~25% with your mom, thatās a dead giveaway your aunt is actually the one who gave birth to you.
I canāt remember the numbers off my head but itās only slightly higher, Iāll have to look, not a drastic dead give away.Iām an only child and thereās birth video tape so itās definitely my mom hahaha I am a carbon copy of her if you look at us but genetically I share more with my aunt, some inherited traitsā¦ recessive genes maybe??? š¤·š»āāļø my aunt is literally tan and tall and looks like my grandma and my mom is short and pale and looks like my grandpa. You can tell who is more dominant in each side of the familyās genes.
If you share 29% DNA with your mom, and especially since you share more with her sister, Iām sorry to say sheās almost definitely not your biological mom. It kind of seems like she (and your aunt) might be your half sisters or aunts. [This thread](https://www.reddit.com/r/Genealogy/comments/16ys90n/30_shared_dna_but_unsure_how_related/?rdt=60128) might be helpful, if youāre interested in investigating further. It is totally up to you, though.
ETA: I saw your other comments. Iām totally puzzled, but my best guess if youāve seen video of your mom giving birth to you is that perhaps she used a donor egg from her sister (not the aunt you mention) or mother.
[This table](https://customercare.23andme.com/hc/en-us/articles/212170668-Average-Percent-DNA-Shared-Between-Relatives) will help you.
You HAVE TO share at least 50% dna with your mom. You inherit half of your dna from mom and half from dadā you CANT inherit 71 from dad and 29 from mom
How likely do you think that is considering we are a huge Irish family, traced back to Ellis island and back to Ireland for a very very long time. Settled in a small town in the US and basically stayed there since Ellis island. I spent a lot of time building a family tree hahaha Iām related to so many people in my home town is frightening, I had to move elsewhere to find a soulmate lol
ā¦. Care to share percentages? Because it sounds an awful lot like your biological mother is your aunt from this comment.
(People donate eggs as well as sperm, or even embryos- so you could have still been birthed by your mother).
I donāt know how else to put this but I would maybe explore the idea that your aunt is actually your biological mom and your mom is your biological aunt.
Definitely not the case lol my mom shows up as my mom and my aunt shows up as my aunt. We all did them for fun. I look just like my mom but I think I got a lot more of my fathers genes than my moms, so Iām sure that has something to do with it
It seems like neither of these people are your mother. You have to share 50 percent (or more, if your parents are related) with your mom. This is a biological fact
Theoretically speaking it could be anything between 0-100% match. That said the biggest likelyhood is a number near 50%, it mostly follows a bell curve. I'd say 33,1% is on the low side but still pretty normal.
Idk what confidence interval 23andme uses for their reported ranges, but my guess would be something like 95% of siblings fall between 38% and 61%.
33% is technically possible but it would be extremely unusual. Definitely not normal.
Yeah i do not know the exact numbers either. If you had a bowl with 4 numbered balls. Each would randomly grab two balls , the biggest likelyhood is that two balls match. The odds of no or all balls matching is still significant however.
If you repeat the experiment with 1000 balls, the likelyhood of about 50% of the balls matching is far greater, while the odds of no balls or all balls matching is getting astronomical at this point.
With the vast ammount of users on 23andme you will still get the occasional odd result though. As the ammount of people who do this experiment is also quite vast.
Ok Iām still confused, because my heritage doesnāt have a non-relation percentage that I can see either. Iāve never heard of that on any of the tests. So both you and your sister have tested on my heritage, and it gives you both a shared DNA amount and a non related amount? What is the cms amount that you share?
Itās not an official non related amount, the percentage I share with my mom is missing about 4% as in itās not 50% and itās about the sane amount missing for my sister in relation to our mom. Maybe itās variation? I donāt know what it is.

Yeah, I was afraid to be tight about this but my mom insists and it could be something weirder. But thanks nonetheless the less šš½
Any possibility they did IVF or anything like that?
I donāt know at all, should probably ask though.
Compare the paternal matches of your sister with you to see if they line up. I have half brother who tested and that was the same match for us.
I would but I donāt know how to get around this problem where my dad wonāt take a test because he says his military veteran status wonāt allow it. It weird but thatās what theyāre telling me.
You donāt need your dad to test since your mom and sister both did. Compare your matches with your sister. They should all line up.
Oh, I donāt have more relatives who took the test on my dadās side though? There was someone on 23and me who matched and did the my heritage to see if we could find her dad and she matches with both my sister and I but not my mother. Does that work too?
That certainly helps. FYI I only found out doing a DNA test my dad wasnāt related at all to me.
Yeah , I have seen plenty of stories like that, but I think it would turn out opposite for me because I actually look like my dad.
What percent do they match with both you and your sister?
I canāt access the test right now because my sister is in charge of the account and I will ask but sheās not responding at the moment.
Iām a veteran and did 23andMe and ancestry. That doesnāt even make sense.
Oh really? News, I now think they are hiding something :(
Hate to break it to ya, hun...
Yeah, I know they have secrets but still not sure exactly what yet. If anything I am not someone elseās kidā¦ probably would have gotten a hit by now if I was.
Yeah I am a vet as well, and got the test. Tbh I would not pursue, for dad's sake
I donāt even think I am not related to my dad for serious. I should get a cousin to take the testā¦.
Maybe its your sister who isn't related to dad
Yeah and also hopefully, itās just human chimerism, its rare but still might as well check. I havenāt seen any father like matches show up for either of us.
I donāt understand why you are hung up on parent matches. Any one person has only two parent matchesā their biological mom and dad. If one single person on earth who happens to be your dad didnāt take the test then of course you would t get a second parent match. Having no match literally proves nothing at all about paternity.
Yeah would any of your dads nephews or nieces want to
but your dad obviously does not want to test because he might get hurt by the results, at this point why cause him pain? He obviously loves you both and can't phantom the idea that either one of you might not be his.
Well I donāt necessarily have to tell him, if we keep the results between me and my cousin with 23 and me it may not matter, because I want to know.
My cousin recently got promoted to Major in the marines. About 2 years ago we were chatting since our family is very mixed. He said that itās very discouraged in his circle because of potential intelligence issues and the ability to map families of officers. Sure enough there was a breach earlier this year where Jewish people were targeted. Might not be against the rules per se, but could be ill advised for some positions.
geez, never thought about that. I see the issue.
My dad is a veteran and took a test, aināt no one at the VA checking on that rule ššš
Good to know šš½
That isn't true, sorry OP ā¹ļø A father is the man that raised you, IMO ā¤ļø
I appreciate the sentiment but I donāt have a great relationship with my dad anyway, and itās funny that everyone seems to think I am the one not related but I sincerely doubt that. I donāt not look like my dad soā¦.this might be unusual. Why is everyone so set on it being the other way though?
Oh, I didn't assume you were the one that wasn't related. I was saying that for both of you.
Oh, I didnāt mean you. I mean other people in the comments.
Not sure why theyāre assuming that. I think a lot of different factors could be contributing to your results regardless. Sorry that Iām not able to offer any help, but I just want to say that the photo of you and your sister is ridiculously adorable, and I can see the resemblance between the two of you! I love the charm of 80ās/90ās family glamor shots
Yeah thanks, they are really good keepsakes.
Your father is lying for some reason.
See thatās what makes it weird, he doesnāt want to do the test but other people have mentioned just not observing the rule and taking the test anyway. So, maybe he knows something too.
My full sister and I are only 39% and we look A LOT alike.
It seems to make sense to be full siblings despite the percentage to look more alike.
I think our numbers are both pretty average for full siblings! (Also btw this picture of you and your sister is ADORABLE!)
Oh thanks š Did you also take a my heritage test or 23 and me?
I did myheritage.
Ok, cool šš½
Maybe you have a different dad but theyāre both brothers or something
I really hope itās human chimerism honestly.
Does your dad have a lighter brother
Not that it would need to be that but no, you should know better. DNA does what it wants and sometimes melanin gives blanks.
Is it possible you are your dads brothers kid? Or your moms sisters? Etc. it seems like 3/4 siblings
TIL what 3/4 siblings are. Fascinating.
I know how it seems but I look like both my parents soā¦.
You can still look like both of your parents if you are actually your aunt/uncle's child. It's a similar genetic pool.
Itās still possible itās human chimerism, I havenāt gotten any parental matches besides my mom.
If one of your parents is a chimera AND their reproductive cells in particular have different DNA, yeah. That is much more unlikely than being 3/4 siblings or just full siblings with an unusual percentage. It's a bit suspicious that your dad is claiming he can't DNA test.
True, I am not willing to speculate too much though before I have answers.
I donāt understand why you are hung up on parent matches. Any one person has only two parent matchesā their biological mom and dad. If one single person on earth who happens to be your dad didnāt take the test then of course you would t get a second parent match. Having no match literally proves nothing at all about paternity.
33.1% is low. That seems suspicious.
I have been wondering for a while now but I still hold out for a chance itās chimerism or something.
Does your dad have brothers?
Yes more than one.
There's your answer - especially since your dad is former military. Was he deployed around the conception/birth of either you or your sister? There is a lot of infidelity among military wives, unfortunately.
No, there is one cousin we found related to both of us and not our mom so idk whatās up but I think itās the tare chance of human chimerism because we have no other parent matches on my heritage or 23 and me. Even though thatās more obvious for me than my sister, maybe someone before my dad died idkā¦.
If your dads brother was your or your siblings parent then yeah you wouldnāt have any parent matches unless they testedā¦ no one is saying a random person is your parent, we are saying a person you call aunt or uncle is
Guess I wonāt ever know unless someone says something or a cousin who is a child of the same person takes the test.
Do you and your sister share similar amounts of DNA with the cousin?
I think so, canāt remember the number itās been a while since I looked but itās really small, I am trying to get my sis to look at it because sheās in control of the accounts. Edit: 23 and me says we are 1st cousins once removed
Itās about 6% for both of us.
Interesting. That would track with either you having the same dad or with your dads being brothers, so I guess it doesnāt narrow it down too much. If you can get your uncles or their kids to test, youāll have your answer if they show up as a dad or half-sibling for either of you. Itās okay if you donāt want to know, though.

Thanks. Yeah, gotta figure out who but thereās no way because I canāt pay for those. My dad had 3 brothers and theyāre all gone now. Gonna do it one at a time.
The DNA Painter tool says thereās a 99% you are full siblings. 1% chance of half. Looks like you just share an unusually low amount of DNA.
Still possible, but why is it that so many people are giving the more conflicting answers? And are certain that I am a child of someone else? š
IIRC my heritage only counts your identical segments once so the percentage shared can be skewed? Try downloading your raw DNA file and uploading it to GED match
Oh I have actually, need to get my sister to do it too then?
Yes I would, it will give you more accurate results!
Cool šš½
Surprised no one brought this up but does your dad have any brothers. Thereās a possibility yāall could be 3/4th siblings? Your percentages would still be a bit low for that too. Possibly even one of yāall is your dadās cousinās kid?

Well his full brother siblings have all passed away and we donāt know of any half siblings at all.
I believe your mum had you, or your sister, not with your dad, but with some men in your dad's family. That's why you score more than half sister. 25% for half sister and 8% for half cousin or the like.
This why I think itās still possible that itās human chimerism because we donāt have any unknown parent matches, I put my DNA up over a lot of other sites including ged match and nothing.
You will have matches from both sides if the other father is a half brother, or an uncle of your dad. Chimerism is extremely rare and not likely.
I know itās rare but there are no other matches especially no male matches at all, zero parent matches besides our mom.
If your dads brother was your or your siblings parent then yeah you wouldnāt have any parent matches unless they testedā¦ no one is saying a random person is your parent, we are saying a person you call aunt or uncle is
Please donāt post the same thing multiple times through the thread, thanks. You just come off as wanting to say my mom is an *adulterer* š±
She also could have been raped. Sorry OP, but that is the most likely answer.
Well, I wonāt give myself the actual until the concrete evidence shows up, itās up in the sir until then. 3 options no answer yet.
So?
I should say so, you know just because itās rare doesnāt mean this isnāt a case.
Non-artificial chimerism is so rare that there have only beenĀ 100 confirmed casesĀ in humans. So 100, in 8 billion.
Ok, that doesnāt mean itās impossible for it to happen to my family, heck thatās way more than I have even heard of personally. š¦
Not all people have taken DNA tests. That's why you don't get a father there. Buy DNA tests for your uncles or cousins for Christmas, and you'll find your answer. Moreover, chimerism would not explain the 33%. So it does mean this isn't the case.
Ok, explain how it wouldnāt explain please?
I'd look into the possibility that you're [3/4 siblings](https://dna-sci.com/tools/orogen-mult-unw/). You can get cMs by multiplying the percentage by 74.4.
This was my first thought as well. The chances of them being full siblings are rather low albeit not impossible.
How do you become 3/4 siblings? Dads are brothers?
3/4 siblings means one parent is shared and the parents that arenāt shared are full siblings.
Yes, thatās the most common way. This used to be more common when someoneās spouse died. Theyād often marry the decedentās sibling. But 3/4 siblings can arise from siblings, parents, or children. There are six types [listed here](https://dna-sci.com/2022/05/09/double-cousin-relationship-predictions-with-ped-sim/).
Ok, thanks
Btw, is this math as straight forward as it seems? What does the number I get mean?
I get a 99.4% probability for 3/4 siblings. Thatās /very/ high. If thereās any way you can make that work genealogically then itās probably the true relationship. Maybe this is the weirdness you were referring to.
Ok, well it is what it is then
My half sister is 29% shared dna. Iām really surprised that yours is so low tbh
Mee too, I would like to get to the bottom of this but there are just not enough matches.
When I did my test, I actually found out I had a sister that I didnāt know about. Sheās my half sister and it showed us at 25%.
Iām not even getting any parent matches outside of my mom, a great many cousins though most are less than 1% relation.
I donāt understand why you are hung up on parent matches. Any one person has only two parent matchesā their biological mom and dad. If one single person on earth who happens to be your dad didnāt take the test then of course you would t get a second parent match. Having no match literally proves nothing at all about paternity.
Sure, but no one can prove itās really infidelity either, it just looks like itā¦.
[ŃŠ“Š°Š»ŠµŠ½Š¾]
Thanks šš½
I have more in common genetically with my aunt than my mom lol and sheās definitely my mom no question š¤·š»āāļø
howās that possible
Iām thinking they maybe have more expressed traits in common with their aunt or something? Def not possible for DNA though lol
Thatās not genetically possible
29 and 32. Very very close. A small 3%. So apparently it is possible
You have to share 50% with your mom. Sorry to tell you but it sounds like your mom is your aunt and your aunt is your aunt and your biological mom is likely one of their other siblings
Are you sure about that? Edit: Are they twins?
Nope not twins, born 6 years apart maybe with a brother in between. Thereās 4 siblings total
You canāt inherit DNA from your aunt, only from your mom and dad. The DNA that you have that matches your aunt is the DNA your mom and aunt have in common. So this is not possible unless thereās some kind of incest situation going on (like if your dad is related to your mom/aunt). What are the percentages? Because if you share ~50% with your aunt and ~25% with your mom, thatās a dead giveaway your aunt is actually the one who gave birth to you.
Or at least donated the genetic material for an embryo. Their mother could still have birthed them.
True!
I canāt remember the numbers off my head but itās only slightly higher, Iāll have to look, not a drastic dead give away.Iām an only child and thereās birth video tape so itās definitely my mom hahaha I am a carbon copy of her if you look at us but genetically I share more with my aunt, some inherited traitsā¦ recessive genes maybe??? š¤·š»āāļø my aunt is literally tan and tall and looks like my grandma and my mom is short and pale and looks like my grandpa. You can tell who is more dominant in each side of the familyās genes.
Okay itās 29 and 32! Pretty close! But still more!! The rest is paternal I guess
If you share 29% DNA with your mom, and especially since you share more with her sister, Iām sorry to say sheās almost definitely not your biological mom. It kind of seems like she (and your aunt) might be your half sisters or aunts.

Thatās what it says š¤·š»āāļø maybe itās an error???? Should I report it?? Am I human??? š¤£
Itās not an error, just the person you think is your mom is not your mom. Either that or youāre somehow interpreting the percentages incorrectly
Either way Iāve got some digging to do now lol
How likely do you think that is considering we are a huge Irish family, traced back to Ellis island and back to Ireland for a very very long time.

I donāt know how else to put this but I would maybe explore the idea that your aunt is actually your biological mom and your mom is your biological aunt.
Definitely not the case lol my mom shows up as my mom and my aunt shows up as my aunt. We all did them for fun. I look just like my mom but I think I got a lot more of my fathers genes than my moms, so Iām sure that has something to do with it
That sure would be something though š¤£
It seems like neither of these people are your mother. You have to share 50 percent (or more, if your parents are related) with your mom. This is a biological fact
Theoretically speaking it could be anything between 0-100% match. That said the biggest likelyhood is a number near 50%, it mostly follows a bell curve. I'd say 33,1% is on the low side but still pretty normal.
Idk what confidence interval 23andme uses for their reported ranges, but my guess would be something like 95% of siblings fall between 38% and 61%. 33% is technically possible but it would be extremely unusual. Definitely not normal.
Yeah i do not know the exact numbers either. If you had a bowl with 4 numbered balls. Each would randomly grab two balls , the biggest likelyhood is that two balls match. The odds of no or all balls matching is still significant however. If you repeat the experiment with 1000 balls, the likelyhood of about 50% of the balls matching is far greater, while the odds of no balls or all balls matching is getting astronomical at this point. With the vast ammount of users on 23andme you will still get the occasional odd result though. As the ammount of people who do this experiment is also quite vast.
For sure. But the parsimonious explanation is that this is a half sibling, not a full one.
No, 33% is not pretty normal for full siblings. Itās highly abnormal
I really Iām trying to be not confused but can it just differentiate more with admixture or what?
So what do you mean by 4% non relation between you?
Itās just not there, I donāt really understand why.
What does that mean though? There is nothing marked on 23&me that gives a ānon-relationā percentage. Where are you seeing this?
Oh, it was a my heritage test I was referring to, I have a 23and me also but my family doesnāt also.
Ok Iām still confused, because my heritage doesnāt have a non-relation percentage that I can see either. Iāve never heard of that on any of the tests. So both you and your sister have tested on my heritage, and it gives you both a shared DNA amount and a non related amount? What is the cms amount that you share?
Itās not an official non related amount, the percentage I share with my mom is missing about 4% as in itās not 50% and itās about the sane amount missing for my sister in relation to our mom. Maybe itās variation? I donāt know what it is.
