Imagine a deleterious recessive allele (a) that is caused by insertion of a transposable element into a gene. Due to high rates of transposition, a new version of this allele is created from the beneficial allele once every 100 generations (mutation rate=1/100). If individuals who are homozygous for this allele suffer a 30% reduction in fitness, what are the equilibrium frequencies of the 3 genotypes?
a) AA: 0.817; Aa: 0.183; aa: 0
b) AA: 0.963; Aa: 0.024; aa: 0.013
c) AA: 0.668; Aa: 0.299; aa: 0.033
d) AA: 0.264; Aa: 0.345; aa: 0.387
e) AA: 0.25; Aa: 0.5; aa: 0.25
The correct answer is C. I just don't know how to work it out.
