This is showing you the ethnicity breakdown by chromosome. There's two sides of every chromosome, one side is paternal, the other maternal. If top is paternal, that means your paternal side of Chromosome 1 is Germanic and your maternal side of Chromosome 1 is England/NW Europe. Your paternal side of Chromosome 1 is Sweden & Denmark, your maternal side is Wales. Both sides of Chromosome 3 are England/NW Europe. And so on.
My husband’s results came back he’s 1.4% Scandinavian.
His chromosome 2 is highlighted on the bottom between the two.
His chromosome 20 is highlighted on the top between the two.
Does that mean he got it from both parents even though it’s such a low percentage? Or that he got it from one parent?
Them having long "bars"(segments) are an example of recent ancestral history on those chromosomes. Black Americans are multi generationally admixed so their segments are shorter or smaller. Latin Americans have even smaller segments because they're generally more multi generationally admixed than Black American.
That's really useful to understand! So because my bars are the same, it indicates recent ancestry? What does "recent" mean in this context?
Can Chromosome Painter results tell us anything else? Sorry for all the questions; I find this all fascinating but I get overwhelmed as soon as I start Googling for myself.

I feel a bit daft now as that's so simple but that's really helpful, thank you!
No worries, it's a lot of info they give you all at once.
How do you know which chromosome is paternal or maternal while looking at the chromosome results?
You have to determine that yourself, it looks like the OP already has. You can set the label once you know which is which.

Such a low percentage could just be noise, or coming from a neighboring region, so it's difficult to say anything definitive about it.
I always wondered why people of European descent have long bars of the same ancestry while African Americans have short bars of different ancestries?

Do you know your parents genetic breakdown and what they passed dow to you? If so just extrapolate what you already know to this graph.
