1a) In a very large population, if the forward and reverse mutation rates are exactly the same, how would you expect the frequency of an original, non-mutated allele to change in the population over time? Will the population eventually achieve an equilibrium value of the frequency of the non-mutated allele? b) What if the forward mutation rate is one order of magnitude larger (e. 10X) than the reverse mutation rate? Do you expect the frequency of the original, non-mutated allele to increase, decrease, or stay the same over time?  c) If the population size is considerably smaller, does this change your expectations for changes in the frequency of the original, non-mutated allele over several generations?
