It just seems like every inter-racial marriage has children that look more black or Asian than they do white. Why is this? Are the white genes less dominant, or do we simply notice the black/Asian/Native American/ whatever features more?How come with mixed-race marriages, the children always look like the non-white parent?
Interesting. Well I think it's a combination of both genetic and psychological factors in perceiving those differences.
This is just speculation but the traits people usually associate with being Asian (eye shape) or black (hair texture) as well as the darker colors of hair, eyes and skin tend to be dominant over lighter colors. Probably not in terms of a single gene, but an interplay of many different genetic factors. This could be the main reason why mixed people tend to look more ';ethnic'; (as people like to say) than white. Other features, like the shape of the nose or face seem like they don't make as much of an impression unless they're very dramatic (moon-shaped face, beak-like nose).
Other than that, however, the genetics are random. And I have seen some people who look more white than their other half. When there's more than a 50-50 ancestry, it definitely gets harder to pinpoint.
In terms of our own perception when looking at these people, it's likely that their non-white traits stand out especially in a crowd of white people. If, say a hapa (half asian half white) were in a crowd of Asians, however, their white traits would likely stand out more. I see this a lot because my university is primarily Asian and anyone with light eyes or hair stands out.
