Hair and eye color are simple epigenetical traits, and very easily measurable. As for size, I don't know if you've traveled to East Asia recently, but the young generations are just as tall as we Westerners. I follow a number of Asian bodybuilders and they aren't any smaller than your average white bodybuilder. The stereotype is likely the product of a historically poor nutrition, but that has changed, and Asians born in the last 30-40 years are proof.
Intelligence, on the other hand, is far more complex to define, measure and test than eye color or height.
