P. 30 The Test Cross
... When an organism has a trait controlled by a dominant allele, it can either be a hybrid or a purebred. To find out which, geneticists can use a test cross. In a test cross, the organism with the trait controlled by a dominant allele is crossed with an organism with a trait controlled by a recessive ...

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.
