a$)$ 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 frequency of the non$-$mutated allele?

Explain. Show any calculations, if you used them to inform your answer. $[2]$

b$)$ What if the forward mutation rate is one order of magnitude larger $($i$.$e$.10$X$)$ 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? $[2]$

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?
