You are wrong here. As the saying goes, the apple never falls far from the tree. Meaning there is a significant overlap between biological parents and their childeren on the personality, cognitive, motoric skills, learning preferences, etc levels.

I've seen the opposite happen with some adopted children. Highly kinesthetic learners stuck with two extremely cognitive learning , high IQ, adoptive parents. Poor kids, there was simply no way they could mirror themselves in their parents nor live up to their adoptive parent's natural expectations. With numerous suicide attempts as a result.

Trying to do good can result in terrible harm. So please, please, be very careful on this issue.
