It has, but in an accidental way, in a, "Shit happens," sort of way, not in a, "My parents looked at me, decided I was faulty, and never gave me a chance," sort of way. This is much more akin to the old practice of leaving babies to die by exposure if they seemed sickly/weak, which still turns my stomach. I think it would even be a different thing to me if we were screening sperm and ova for their genes and only combining the best sets than screening the embryos.
