Essay

A population of lab rats recently escaped into the sewer system of Washington,D.C.A brave researcher sampled this population and estimated the following phenotypic frequencies,which were caused by a single gene with two alleles: E and e.
61% normal eyes(EE)
26% cross-eyed(Ee)
13% blind(ee)

a)If this population were to reach a Hardy-Weinberg equilibrium (HWE)in one generation,what would the phenotypic frequencies be in that new HWE generation?
b)Suppose that the phenotypes of the original adult population were not equally likely to survive and reproduce (selection).The fitness coefficients are as follows:
$$\mathrm { W } _ { E E } = 1 \quad \mathrm {~W} _ { Ee } = 0.6 \quad \mathrm {~W} _ { ee } = 0.2$$ What would be the expected phenotypic ratio of babies in the next generation (if selection acts only on adults)?
