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

260 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?

Imagine your body is like a big instruction book that tells it how to work. Chromosome 12 is like one chapter in that book. It’s a tiny, tiny thing inside your body’s cells that carries important information. Just like a recipe card helps make yummy cookies, chromosome 12 helps make you!

Chromosome 12 exists because our bodies are super complicated, and they need lots of instructions to work properly. It’s like a special code that tells your body how to build and do everything. It’s made up of something called “DNA,” which is like a bunch of tiny beads on a string.

This special chromosome 12 has a job in deciding what you look like and how you work. It’s a bit like how different puzzle pieces make different pictures. The information on chromosome 12 helps your body know things like what color your eyes and hair will be, how tall you might grow, and even some things about your personality.

So, in short, chromosome 12 is a tiny part of you that holds important information, like a recipe for making you. It’s like a puzzle piece that helps create your look and how your body functions.
