Title: lethal dominant alleles Post by: confused_student on Nov 11, 2010 Under what circumstances might a lethal dominant allele perisist in a population? Give an example in humans.
Title: Re: lethal dominant alleles Post by: bio_man on Nov 11, 2010 Since a dominant lethal gene is highly selected against, it is unlikely that it will exist at too high of frequency, if at all. However, if the gene shows incomplete penetrance or late age of onset (after reproductive age) it may remain in a population.
