How are allele frequencies calculated

WebGiven genetic data, allele frequencies by population are calculated. This estimation method assumes polysomic inheritance. For genotypes with allele copy number ambiguity, all alleles are assumed to have an equal chance of being present in multiple copies. This function is best used to generate initial values for more complex allele frequency ... 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 …
