Question 1. Consider the Wright-Fisher model for two alleles 1 and a with N = 4 individuals and initial allele frequency f4(0) =0.875. (a) What is the probability that the 4 allele becomes fixed in generation 1? (b) What is the probability that the 4 allele eventually becomes fixed? (c) What is the expected allele frequency in generation 100? (d) What is the probability that the A allele frequencies in generations 1 and 2 are the same as the A allele frequency in generation (? (e) Would any of your answers to (a), (b) and (c) change if the population size was N = 8 instead? If so, recalculate them. If not, explain why not
