In a population of 50,000 diploid yeast cells (in this case the census and effective population sizes are identical) all cells have genotype A until a mutation (A-a) occurs, giving one copy of a. Alleles confer equivalent fitness.
a. What is the probability that a will be fixed?
b. How long will it take a to become fixed on average (include units)?
c. The same mutation occurs in a haploid population of 500 bacterial cells. What is the probability that a will be fixed?
d. If a is fixed, how long will its fixation take on average (include units)? Remember that in this particular example, this organism is haploid.
