Nonrandom mating (for example, assortative mating) directly affects gene frequencies in populations.

Question

Quizplus · Accepted Answer

Nonrandom mating, such as assortative mating, affects the distribution of genotypes within a population but does not directly change allele frequencies. It can lead to changes in genotype frequencies and can increase the proportion of homozygous individuals, but the overall allele frequencies in the population remain unchanged unless accompanied by other evolutionary forces.
