Consider a population and a gene with two alleles, one found at a frequency of p, and the other at a frequency of q, what equation represents the sum of all allele frequencies in the population?Multiple choice question.p + q = 1p + q + pq =1p + q = 2.p + q = 2pq
Question
Consider a population and a gene with two alleles, one found at a frequency of p, and the other at a frequency of q, what equation represents the sum of all allele frequencies in the population?Multiple choice question.p + q = 1p + q + pq =1p + q = 2.p + q = 2pq
Solution
The correct answer is p + q = 1. This equation represents the sum of all allele frequencies in a population. In population genetics, the frequencies of two alleles in a gene pool always add up to 1. This is known as the Hardy-Weinberg equilibrium.
