1 a. You observe a population with 4000 zygotes with the genotype AA, 800 zygotes with the genotype Aa, and 50 zygotes with the genotype aa.

a. What are the frequencies of the three genotypes and the A and a alleles in the zygotes?

b. You come back later to this population and determined there are the following number of juveniles. 3,000 AA; 700 Aa; and 12 aa genotype. Calculate the relative fitness w, and the selection coefficient for each of the 3 genotypes.

c. Calculate normalized genotype frequencies after selection.

d. Calculate allele frequencies after selection.

e. What kind of selection is occurring and what will be the equilibrium allele frequencies?

2a. Calculate the change in allele frequency under the island-continent model for gene flow under the following two conditions

m = 0.5, = 0.2, Pc = 0.9 m = 0,5, = 0.85, Pc = 0.9

What is happening to the frequency of the allele on the island and what will be the eventual outcome? In which case is the rate of change slower and explain why?

2b. Calculate the change in allele frequency under the island-continent model for gene flow under the following two conditions

m = 0.1, = 0.2, Pc = 0.9

m = 0,9, PI = 0.2, Pc = 0.9

What is happening to the frequency of the allele on the island and what will be the eventual outcome? In which case is the rate of change slower and explain why?
