Recessive and dominant heredity in humans
... If a deadly mutation occurred that was dominant, people with either Dd or two DD would die out. The only surviving people would be recessive dd and would only have other dd people to have children with. The population would be disease free as the D allele would quickly go extinct. Many of these alle ...
