WebHardy Weinberg law states that genetic variations remain constant in a large, randomly mating population. The frequency of alleles and genotypes remains constant from generation to generation and the population exists in a genetic equilibrium if there are no disturbances such as mutation, migration, natural selection, etc. WebAs we will see below, the Hardy-Weinberg principle provides us with a mathematical equation to calculate the expected frequency of an allele in a population. P 2 + 2 PQ + Q 2 = 1. P: dominant homozygous frequency (AA) 2 PQ: heterozygous frequency (Aa) Q²: recessive homozygous frequency (aa) 1: 100% of the population. asia 63
