I've heard there's a gene that's associated with higher desire to explore new places. And the highest frequency of that gene is among native South American population. They apparently went farther than anyone from Africa.
The least I could think of myself as a racist.
UPDATE: I think I see your point. We have many interesting genes, myself included, none of them defines us as a person. I think it's irrelevant.
But in my comment I expressed a connection between a population statistical gene expression and a particular family. That is a tiny bit racist, agree. :(
