The advantage of outbreeding over inbreeding, and why inbreeding is avoided in humans and other primates, is that it
A) reduces the risk of the expression of deleterious alleles.
B) reduces the risk of heterozygosity.
C) increases the likelihood of the expression of deleterious alleles.
D) increases the likelihood of homozygosity.

Question

Quizplus · Accepted Answer

Outbreeding increases genetic diversity by introducing new alleles into a population, which can reduce the expression of deleterious recessive alleles. Inbreeding, on the other hand, increases the likelihood of homozygosity, which can increase the expression of deleterious recessive alleles. In humans and other primates, inbreeding is avoided to reduce the risk of genetic diseases that can result from the expression of deleterious alleles.
