Are you joking or pushing some eugenic agenda? Genetic defects are
typically recessive. That means there are so many carriers that the fact
that those who have the disease survive does not affect much of the
total gene-pool. Everyone of us carries several genetic diseases, so if
you want to perform eugenics, then start form yourself.
