Why are lethal dominant alleles so much more rare than lethal recessive alleles?
a. the lethality associated with lethal dominant alleles is much more severe than that associated with lethal recessive alleles.
b. the types of mutations that create lethal dominant alleles are much less frequent than those that create lethal recessive alleles.
c. less is known about lethal dominant disorders, so the rareness of these alleles is an artifact due to a lack of detection.
d. lethal dominant alleles are harmful whether they are carried in homozygous or heterozygous form, so there is always strong selection against these alleles.
