Question
. (Natural Selection) A new mutation at the T locus has arisen in the squirrel population on UNC?s campus. The allele makes the coats of heterozygotes Carolina blue. A curious undergraduate wonders if there is a selection advantage due to students giving these squirrels extra food handouts. He counts the number of each genotype in early summer just following a breeding and again just before breeding in the winter. His results were as follows: a. Calculate the Absolute Fitness's of the three genotypes: TT, Tt, and tt. b. Calculate the Relative Fitness's of the three genotypes: TT, Tt, and ft. e. What will the equilibrium frequency of the T allele be in this population if this trend continues for many generations?Explanation / Answer
Absolute fitness of TT---- 3500 / 1600 = 2.18
Tt ----- 400/350 = 0.5
tt ---- 200/150 = 1.33
relative fitness ----
TT ----- 2.18/2.18 = 1
Tt ----- 1.14 / 2.18 = 0.5
tt ---- 1.33 / 2.18 = 0.61
