The correct answer is: A.The frequency of each genotype in a population

Explanation:

The Hardy-Weinberg equation, p² + 2pq + q² = 1, helps to determine the frequencies of the genotypes in a population based on the frequencies of the alleles. Here’s what each term represents:

1.p²: The frequency of the homozygous dominant genotype (AA).

2.2pq: The frequency of the heterozygous genotype (Aa).

3.q²: The frequency of the homozygous recessive genotype (aa).

By using the allele frequencies p (for the dominant allele) and q (for the recessive allele), the equation predicts the expected genotype frequencies in the po...
