Multiple Choice

When calculating the allele frequency of allele A in a population, why do you multiply the frequency of individuals who are homozygous for A by 2?

A) Because if A is dominant, it will show up twice as much.
B) Because each individual who is homozygous for A has two copies of the allele.
C) Because there are always twice as many homozygous individuals as heterozygous individuals.
