Question

Quizplus · Accepted Answer

Deviations from Hardy-Weinberg equilibrium occur when evolutionary forces such as mutation, selection, genetic drift, migration, and non-random mating are operating on the population. This can result in changes in allele frequencies and genotypic frequencies, which can deviate from the expected values under Hardy-Weinberg equilibrium.
