Question

8. A population of red bats has two alleles (A and B) at the chymase gene. The relative fitness values of the three genotypes are WA0.9, WA - 0.9, and wAA1.0. At time 0, the frequencies of the two alleles are f(A)p 0.5 and f(A) q 0.5. a. What type of selection is operating at the chymase gene? b. Which allele (A, A; or neither) is genetically dominant? c. Calculate s for this locus. d. Calculate the average fitness of this population e. What will the frequency of the A allele be in generation 1?

Explanation / Answer

b.The relative fitness for A'A' is highest that means this genotype is most fit amongst the three so this genotype is the dominant over AA.
