Figure 19.1 C. 1: The Hardy-Weinberg Principle: When populations are in the Hardy-Weinberg equilibrium, the allelic frequency is stable from generation to generation and the distribution of alleles can be determined. WebASK AN EXPERT. Science Biology Albinism in humans is a relatively rare recessive condition. Let the allele for normal pigmentation be A and the allele for albinism be a. Therefore, individuals with the genotypes AA and Aa are normally pigmented individuals and aa are albinos. Suppose that in the US the frequency of albinos is 1 in 10,000.

WebThe allele frequencies for a gene with two alleles are usually represented by the letters p and q, where the relative frequency of the B allele is p and the relative frequency of the b allele is q. WebTo determine what the actual frequency is, simply divide 98 200 = 0.49. We now know that q2 = 0.49. However, we wish to find the frequency of the population that is heterozygous, which is equal to 2pq. So, we must find both p and q. Finding q: q2 = 0.49 Take the square root of both sides. q = 0.7
