The only assumption we have used is that the sample is a random sample. Starting with these genotype frequencies, we can estimate the allele frequencies without making any further assumptions: Out of 20,000 alleles in the sample, 442+10.0226 are 20,000 WebThe formula is basically the same except the number of allele frequencies plugged into the formula increase. For example, a gene with 3 possible alleles (Eg. A1, A2, A3) will have the formula: (p + q + r)2 = 1, which is the same as p2 + q2 + r2 + 2pq + 2pr + 2qr = 1. mika in real life goodreads
