The homozygote, aa, has a selective coefficient of s = 0.25. Assuming that the population prior to selection is in Hardy–Weinberg equilibrium and that the allele frequency of the A allele is 0.7, what will be the allele frequency of (a) after one round of selection?
a. 0.7201
b. 0.2815
c. 0.3088
d. 0.7592
