A Genetic Study Conducted Over Two Generations Found That the Frequency

question 10

Multiple Choice

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:

• 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.
