The correct answer is: C.P² + 2pq + q² = 1

 

Explanation:

This equation represents the genotype frequencies in a population under Hardy-Weinberg equilibrium, where:

1.P² represents the frequency of the homozygous dominant genotype (AA),

2.2pq represents the frequency of the heterozygous genotype (Aa),

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

The sum of these frequencies is always 1 in a population that is in Hardy-Weinberg equilibrium.
