Well, solely with respect to skin color, which is arguably THE single biggest physical characteristic of concern... Yeah, I'd say >95% of Americans consciously select their mates with skin color in mind. Google the rates of interracial marriage if you don't believe me.
And yes, the skin/eye/hair color of the parents is probably about 99% determinant in the perceived race of the children... There are always exceptions, but two random people who are "white passing" are overwhelmingly likely to have children who are also "white passing".
You can call this behavior "eugenism" or even just racism, and I'm not saying your terminology is wrong... But I dare you to start going around telling people that to their faces.
