Selection, Gene Pools, Hardy
... Differences between reality and these predictions can help us figure out how selection and mating are really working! Under Hardy-Weinberg equilibrium, the frequency of homozygotes for an allele is equal to the square of that allele's frequency. In other words, if p represents the frequency of W ale ...
