Nonrandom mating alters the frequencies of the genotypes but not the frequencies of the alleles. Inbreeding is preferential mating between related individuals. With inbreeding, the frequency of homozygotes increases, whereas the frequency of heterozygotes decreases.
-What is the effect of outcrossing on a population?
A) Allelic frequencies change.
B) There will be more heterozygotes than predicted by the Hardy-Weinberg law.
C) There will be fewer heterozygotes than predicted by the Hardy-Weinberg law.
D) Genotypic frequencies will equal those predicted by the Hardy-Weinberg law.

Quizplus · Accepted Answer

Outcrossing increases the frequency of heterozygotes in a population, leading to more heterozygotes than predicted by the Hardy-Weinberg equilibrium, which assumes random mating.
