This document discusses population genetics concepts, including gene pools and allele frequencies. It defines a gene pool as the total set of genes in a population, consisting of all alleles at all gene loci in all individuals. Allele frequency is the ratio of a given allele to all alleles of that gene in the population. For a gene locus with two alleles, the frequencies of the alleles (p and q) must sum to 1. If the allele frequencies do not change between generations, the gene pool is considered to be in genetic equilibrium.
