WebSep 12, 2024 · How do you calculate p and q allele frequencies? To determine q, which is the frequency of the recessive allele in the population, simply take the square root of q2 which works out to be 0.632 (i.e. 0.632 x 0.632 = 0.4). So, q = 0.63. Since p + q = 1, then p must be 1 – 0.63 = 0.37. WebA person has type O blood only if they are homozygous for the O allele at the ABO locus. The frequency of the O allele is 0.67 in the United States. A person’s blood is Rh+ if he or she is homozygous or heterozygous for the D allele at the Rh locus, which has an allele frequency of 0.6. Assuming no linkage disequilibrium between
