Consider a population that is in Hardy-Weinberg equilibrium at a locus with two alleles, A and a, at frequencies of p and q, respectively. Assuming the population remains in Hardy-Weinberg equilibrium, what is the expected frequency of Aa heterozygotes after 100 generations? A) 1 B) 2pq C) 0.5 D) p²

Quizplus · Accepted Answer

According to Hardy-Weinberg equilibrium, the frequency of Aa heterozygotes can be calculated using the formula 2pq, where p and q are the frequencies of the A and a alleles, respectively. Since the population is in equilibrium, the frequencies will remain constant over time, so the expected frequency of Aa heterozygotes after 100 generations is still 2pq.
