Answer to Question #73906 in Genetics for Jingyu Wang
(A) [10%] Calculate the change in allele frequencies in the predator per generation. Simplify your equations.
(B) [10%] Assume now that allele B in the prey is disadvantaged if allele A is common in thepredator. ThuswB =1−fAs + t,wheres and tareselectioncoefficients. Calculatethe change in the allele frequencies in the prey in one generation. Simplify your equations.
(C) [5%] Is there a non-trivial equilibrium for fA and fB such that ∆fA = 0 and ∆fB = 0? By non-trivial, we mean when neither A nor B has frequency 0 or 1. If a non-trivial equilibrium exists, then characterize it?
