Two alleles of the ldh gene occur in house flies, f and s. the table provides the number of offspring produced for individuals in of the three genotypes when raised in a lab environment.
w
ff
0.984
fs
1.200
ss
1.128
a) calculate the relative fitnesses rescaling them so that fs has a fitness of 1.0
b) calculate the average excess of fitness for the f allele when it is at a frequency of 0.2. will the frequency of a1 increase from 0.2, decrease, or stay the same?
c) calculate the stable equilibrium frequency at which the f and s alleles would be expected to persist in the laboratory population. use the equation given in lecture 6 (frequency-dependent selection): peq= t / (s + t)
