Eli5 I recently did an AncestryDNA test to learn about what makes me up. Can anyone explain what chromosome 12 is?

I don’t know anything about chromosomes and google is further complicating it for me. I’ve always looked quite different from my peers and I wondered if there was something mixed in with me that would cause that, it turns out I have Scandinavian. In the chromosome breakdown part of the results it says that the Scandinavian is in chromosomes 12 and 21. Can anyone explain to me what this MEANS. Would that affect my physical appearance? Like my facial features? If not, what does it mean?

When there’s a specific gene for something, we know what chromosome it’s on. Eye color, which is relatively simple, involves at least eight genes across multiple chromosomes, but the most important one is on chromosome 15.

Facial features have too many factors to be on one chromosome. It’s not impossible that there could be some quantifiable difference between people with “scandinavian” 12 and 21 vs 5 and 9, but we don’t know what it is.

You’re you. I hope your peers are genetically diverse and look different from each other, too.

It sounds like you might be hung up on trying to explain your differences. I hope you can embrace yourself for who you are.
