Does Brazil produce the best supermodels because it's a country where Europeans change their gene pools?

Question

Many supermodels have two European parents (both from different countries); and Brazil is a haven for Europeans with different ancestry to interact and mate--thus changing their gene pools for the first time (take for instance Allesandra Ambrosio: her father has nothing but Italian ancestry while her mother has nothing but Polish ancestry). Many white Americans have too many ancestries to count; is that why there are so few American models?

Answer 1

This is NOT a genealogical question!

Answer 2

*****Not necessarily.  I think your question could better be answered by a group that is focused on genetics, not genealogy.
