I'm unwilling to register at the site on vague principle but I think I can attest to the fact that ethnicities vary in their phenotypes. I have family members who are Japanese, Chinese, Fillipino as well as African American and about a dozen different European ethnicities, Jews and gentiles. We are a varied and mixed lot. Yes I think I can distinguish Chinese from Japanese but some individuals in each population, due to geography and politics are often a mix. Within each population are individuals who closely resemble another group.

It's usually a problem depending on appearances and it strengthens to point that, underneath we are all pretty much the same.

It's not a real registration, just enter fake info.

I thought so too and I did pretty well, but not perfect. Try it.
