Philosophy genetics
What would happen if a very cognitively slow man who was product of generations of inbreeding had a child with a very intelligent doctor? What would the child be like? Would it be 'average' in intelligence or healthiness? Would the intelligent doctor genes override the poor genetic quality of the man to make a healthy child? Would the child inherit more of the doctor genes because they enhance survival?

The idea of a ' cognitively slow' person raises a lot of questions in itself. What on earth does it mean to be labelled cognitively 'slow'. Also, the factors leading to learning disabilities are numerous, and not always genetic
Genetics is unpredictable. Two people who have exceptionally high IQs won't necessarily have a child that does. Also, genetics is about dominant genes and can have various results. In particular, children of a set of parents may not all look alike at all.
Also, take into account the fact that if fetuses show signs of severe physical and mental defects that would result in a poor quality of life compounded by an added burden to taxpayers' money, couples opt for abortion. A big hint, by my reckoning, that people want what you think and say they want.
For better or worse, we currently lack the knowhow to engineer babies. Also, can the existing socio-economic structures support such a policy? Can the world, in its current form, handle a situation in which everyone is a doctor or an engineer or a supermodel or a scientist? God knows.
