Two things I’ve learned as a result of having an offspring with Chinese + Caucasian genes: 1) Caucasians typically have wet ear wax, which is, alas, dominant (I first thought the weird gunk in my son’s ears meant he was sick). 2) Caucasians don’t have “shovel-shaped” teeth like most Chinese people do (I don’t have a great web link for this one). My genes appear to have won in the teeth department, but I’m not aware of any benefits there.
