WebTo find the allele frequencies, we again look at each individual’s genotype, count the number of copies of each allele, and divide by the total number of gene copies. Now, we find the frequency of W has dropped to 8/18 = 0.44 8/18 = 0.44, or 44%, and the frequency of … It is p2+ 2pq+q2 because you are talking about the frequency of alleles and we … WebThe Hardy-Weinberg principle is derived from this table.

WebYes Hardy-Weinberg is mainly used to calculate the expected frequency assuming: no mutations, no gene transfer, random mating, large population, and no selection. However if we know the actual frequency of the homozygotes (i.e. p^2 and q^2) in the actual population we can compare to an expected value.

The expected allele frequency spectrum may be calculated using either a coalescent or diffusion approach. The demographic history of a population and natural selection affect allele frequency dynamics, and these effects are reflected in the shape of the allele frequency spectrum.
