question 17

Multiple Choice

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

• A) negative assortative mating has maintained gene frequencies.
• B) mutations have likely occurred, resulting in the same frequency.
• C) mating in this population is random.
• D) the population is small and we cannot detect change.
