Answer :
Final answer:
The frequency of the AA genotype in the next generation remains 0.4.
Explanation:
The frequency of the AA genotype in the next generation can be calculated using the Hardy-Weinberg equation p² + 2pq + q² = 1. In this equation, p represents the frequency of the dominant allele (A) and q represents the frequency of the recessive allele (a). Given that p = 0.4 and q = 0.6 in generation 1, we can substitute these values into the equation to find the frequency of the AA genotype in the next generation. Plugging in the values, we get (0.4)² + 2(0.4)(0.6) + (0.6)² = 0.16 + 0.48 + 0.36 = 1. In the next generation, the frequency of the AA genotype remains 0.4.
