How to find the relative frequency
Taking the square root, we find that the allele frequency of q (white) is 0.4, or 40%. Finding p. Once we know q, we can simply subtract q from 1 to find the frequency of p. This works only in a simplified scenario, where p and q are the only alleles and account for 100% of the total alleles. In this case, p will be equal to 60% of the alleles ...
