keep track of changes in genotype frequencies from generation to generation in a population.

determine what evolutionary mechanisms are causing changes in a population’s gene pool frequencies.

Detailed explanation-1: -p2 + 2pq + q2 = 1 mathematically represents Hardy-Weinberg’s principle used to calculate the genetic variation of a population at equilibrium. It states that the allele frequencies in a population are stable and remain constant from one generation to another.
Detailed explanation-2: -In the equation, p2 represents the frequency of the homozygous genotype AA, q2 represents the frequency of the homozygous genotype aa, and 2pq represents the frequency of the heterozygous genotype Aa.
Detailed explanation-3: -1 Answer. The gene pool i.e., the total genes and their alleles in a population tend to remain constant, This is called genetic equilibrium. Sum total of all allelic frequencies is 1 Individual frequencies, can be named p, q, etc. In a diploid, p and q represent the frequency of allele A and allele n.
Detailed explanation-4: -p = frequency of the dominant allele in the population. q = frequency of the recessive allele in the population. p2 = percentage of homozygous dominant individuals. q2 = percentage of homozygous recessive individuals. 2pq = percentage of heterozygous individuals.
