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

306 views

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?

All that means is that you have some DNA that is more common in Scandinavian countries on those chromosomes. There may not be enough to express itself in any of your features.

That is, of course, assuming that the test is accurate in the first place.
