Well...if we all look back far enough we all came from black ancestors in south africa.
So I guess we all could check the african-american box.
You cannot get much whiter than my skin is. My hair is blonde, eyes blue. Yet I used to work in an HLA tissue typing lab back in college and they loved my blood for its interesting HLA types, so I'd donate a few tubes for lunch money. At least one of my genes is African. It's found in some Jews like me. I find the whole thing interesting. Maybe I will have this done if it's not too expensive.
