WebTo determine what the actual frequency is, simply divide 98 200 = 0.49. We now know that q2 = 0.49. However, we wish to find the frequency of the population that is heterozygous, which is equal to 2pq. So, we must find both p and q. Finding q: q2 = 0.49 Take the square root of both sides. q = 0.7 WebAllele frequency formula. The formula for genotypic frequencies is p 2 + 2 p q + q 2 = 1 where p 2 is the homozygous dominant frequency, the q 2 means the homozygous …

WebThe frequency of each allele may now be calculated from these data, remembering that we have let p, q and r represent the frequencies of genes I A, I B, i respectively. The value of r, that is, the frequency of gene i, is immediately evident from the figure given: r 2 = 0.444, hence r = √0.444 = 0.6663 (= frequency of i) WebD is the dominant allele for black (Carbonaria) d is the recessive allele for white (Typica) Genotype DD or Dd = Black moths (Carbonaria) Genotype dd = White moths (Typica) Hardy Weinberg equations: 1 = p + q 1 = p2 + 2pq + q2 where p is the frequenc ….
