What if his mama believed in abortion?
His mama probably came to this belief - too late to make a difference.
The list of conditions they can diagnose before birth is growing, approaching a thousand from a single amniocentisis, and they can diagnose some conditions now through blood tests of the mother by identifying the fetus’ DNA floating in her blood. The idea is that if she can be diagnosed at 3 months along instead of five or six, it is easier to terminate if something is wrong.
There are genetic correlations to personality traits. We could easily see tests in 10-20 years that show a strong likelihood to one political affiliation or personality types (those with addiction to adrenaline tend to be risk takers, Democrats/liberals are very difficult to offend, conservatives are security oriented compared to liberals).
Imagine genetic tests for personality traits and screening out everything from introverts to conservatives to the guy most likely to be the next astronaut on Mars because he is too likely to break bones doing stunts at the indoor trampoline place.
