I have two children. At the moment, all I know about their genes is that they both have 46 chromosomes, and one is XY and one is XX.

I try to treat them equally, to assume equal potential. But what if I knew my daughter carried a “smart” gene and my son did not? When he came home from school with a B, would I assume it was because of his genes and not push him to try harder?
