Blondes are desired, not black girls. I don't know if caucasian genes are more craved than other races. Meaning that, from a very unjaded perspective by "cultural indoctrination" of what attractiveness is, that caucasians are actually scientifically more attractive than the non white races. What do you think?
“I could show fight on natural selection having done and doing more for the progress of civilization than you seem inclined to admit. Remember what risk the nations of Europe ran, not so many centuries ago of being overwhelmed by the Turks, and how ridiculous such an idea now is! The more civilised so-called Caucasian races have beaten the Turkish hollow in the struggle for existence. Looking to the world at no very distant date, what an endless number of the lower races will have been eliminated by the higher civilized races throughout the world.”
― Charles Darwin
