A genetic study conducted over two generations found that the frequency of genotypes in the first generation were,AA: 0.36,Aa: 0.48,aa: 0.16.In the second generation,genotype frequencies remained the same.According to Hardy-Weinberg equilibrium,we can assume:

Question

Quizplus · Accepted Answer

Hardy-Weinberg equilibrium assumes that mating is random, so if the genotype frequencies remained the same in the second generation, it suggests that mating in this population is random. Option A, negative assortative mating, would result in a change in gene frequencies over time. Option B, mutations, could also result in changes in gene frequencies. Option D, a small population size, could lead to genetic drift and changes in gene frequencies over time, but since the frequencies remained the same, this option is not applicable.
