We will talk about this more in class, but pigeons have a gene, EphB2, that controls head crest feather development. A recessive allele at this locus reverses the feathers on their head crests and basically makes them look like they have a huge cowlick. There are 100,000 pigeons in the population; 1,000 pigeons are heterozygous for the recessive trait; and 1,674 pigeons have reversed head-crest feathers. If we call the dominant allele A1 and the recessive allele A2, which of the following is closest to the frequency of the A2 allele?

Select one:
a. 0.973
b. 0.978
c. 0.017
d. 0.022
