Hardy-Weinberg law


Hardy-Weinberg law
Mathematical formula that gives the relationship between gene frequencies and genotype frequencies in a population. If genotypes are AA, Aa, aa and the frequency of alleles A,a are respectively p,q, then p+q=1 and AA:Aa:aa is p2 :2pq:q2. Deviation from this equilibrium distribution suggests adverse survival characteristics of organisms with one of the alleles.
