There was a sperm donation bank somewhere in Europe where all the sperm donors were extraordinary, like Nobel laureates, very attractive, etc. basically the cream of the crop. Almost always, women wanted a sperm donor who looked like their husband, even if he was short, dumb, fat and bald and they could choose anyone.

Maybe something similar happens for parents with kids. They want the kid to be just like them. Idk, but I’m curious what would be popular.
