The formula p² +2pq + q² represents the Hardy-Weinberg equilibrium equation, which predicts the genotype frequencies of a population. If a population is in genetic equilibrium, it means that the allele frequencies are not changing and therefore the genotypic frequencies of the population remain constant from generation to generation. In equilibrium, p² represents the frequency of homozygous dominant individuals (AA), 2pq represents the frequency of heterozygous individuals (Aa), and q² represents the frequency of homozygous recessive individuals (aa). If we add these frequencies together, we get p² + 2pq + q²=1, which means that all the genotypic frequencies add up to 100% of the population. Therefore, the correct answer is C)1.
