Answer: The correct answer is-
genotype frequencies.
Hardy-Weinberg equilibrium is a condition according to which frequency of gene variant in the population of sexually reproducing individuals remains constant over generations ( that is it does not change from one generation to another generation).
There is an equation for the Hardy Weinberg law, which helps in determining the genotypes ( such as frequency of homozygous dominant, heterozygous domiant, and homozygous recessive genotypes). The equation is-

Where p² represents the homozygous dominant, 2pq represents heterozygous domiant, and q² for homozygous recessive genotypes.
