Question

In the Hardy-Weinberg equation,2pq refers to
A) the proportion of heterozygotes in a population.
B) the number of homozygous dominant individuals in a population.
C) the most common phenotype in a population.
D) individuals who are homozygous recessive.
E) individuals with a mutation.

Accepted Answer

2pq in the Hardy-Weinberg equation represents the proportion of heterozygotes in a population. The equation is p^2+2pq+q^2=1, where p and q represent the frequencies of the dominant and recessive alleles, respectively. 2pq represents the frequency of heterozygotes, as they have one copy of each allele.
