Which of the following processes will result in more heterozygotes than expected under Hardy-Weinberg?
A) disassortative mating
B) directional selection
C) frequency-dependent selection
D) mutation

Question

Quizplus · Accepted Answer

Disassortative mating occurs when individuals mate with those who have dissimilar traits, resulting in an excess of heterozygotes. This is in contrast to assortative mating, where individuals mate with those who have similar traits and results in an excess of homozygotes. The other options (B, C, D) do not necessarily result in an excess of heterozygotes under Hardy-Weinberg. Specifically, directional selection and frequency-dependent selection may result in a decrease in heterozygotes, while mutation can introduce new alleles but does not necessarily affect the frequency of heterozygotes.
