The stable frequency distribution of genotypes, aa, aa, and aa, in the proportions p 2, 2pq, and q 2 respectively where p and q are the frequencies of the alleles, a and a that is a consequence of random mating in the absence of mutation, migration, natural selection, or random drift. Deze wet is geldig in een stabiele geen migratie populatie over verschillende generaties. Hardy weinberg equation this equation is used to predict or explain the relative freqencies of alleles and different phenotypesgenotypes in a stable population, i. The hardyweinberg equilibrium principle describes the unchanging frequency of alleles and genotypes in a stable, idealized population.

Making sense of hardyweinberg equilibrium one of the more difficult topics for introductory biology students to understand and for teachers to teach is the hardy w einberg. If paolos polymorphisms are all snps then he may also want to download and install hwqtl which is use to perform hardyweinberg equilibrium tests for multiple snps, which is what i think paolo is trying to program. Since the a and b loci each have only two alleles pres ent in the population, the frequencies for each locus p and q must add to 1.
