Question

Quizplus · Accepted Answer

Inbreeding is a form of nonrandom mating, but it actually decreases the proportion of heterozygotes in a population, not increases it. Nonrandom mating can lead to other effects such as increased homozygosity and reduced genetic diversity, but it does not necessarily cause subdivision into two phenotypic classes. The other options are true statements about nonrandom mating.
