A gene has four alleles, A1, A2, A3, and A4. The alleles occur in a population at the following frequencies: A1=0.2, A2=0.1, A3=0.4, A4=0.3. Compute the following:

a) Probability that a single allele chosen at random is either A1 or A4

b) Probability than an individual as two A1 alleles

c) Probability that an individual has one A1 and one A3 allele

d) Probability that an individual is NOT A1A1

e) Probability that if we drew two individuals at random, neither would be A1A1

f) Probability that if we drew two individuals at random, at least one would be A1A1

g) Probability that three randomly chosen individuals would have no A2 or A3 alleles

Assume that the allele frequencies of alleles A1 and A2 were 0.2 and 0.8 in one subpopulation and 0.4 and 0.6 in another subpopulation. Assuming that there are Hardy-Weinberg proportions within each subpopulation and that the subpopulations are of equal size, what would be the observed heterozygosity if these populations were lumped? How does this compare to what would be expected if there were one random-mating population?? Calculate the same values for the three heterozygotes when the subpopulations had frequencies...

4. Say we have a population, with Ne = 100, containing two alleles, A1 and A2 at frequencies 0.6 and 0.4, respectively. We leave this population alone for 10000 generations (keeping its size constant), then come back to find that the allele frequencies are still 0.6 and 0.4. a) Explain why this would be evidence that selection is acting in this population. b) Which genotype would you expect to have the highest fitness in this case? Explain.
