I am raising a populationof Halloween cats - they have either black tails or orange tails. tail color is determined by a single gene with only two alleles: B is for a black tail and black is dominant; b represents the allele for the recessive trait, an orange tail.In a population of 200 cats, 32 of the cats have an orange tail. Assuming Hardy-Weinberg equilibrium, what is the frequency of homozygous recessive individuals in the population?
If a population follows Hardy-Weinberg equilibrium, the relative frequencies of each genotype can be estimated based on the relative frequencies of the alleles, p and q, with p as the relative frequency for the dominant allele and q for the recessive allele. The frequency of homozygous dominant can be computed as p2, for heterozygotes, it is 2pq, and homozygous recessive as q2.
