Recurrent mutation causes changes in the frequencies of alleles. At equilibrium, the allelic frequencies are determined by the forward and reverse mutation rates. Because mutation rates are low, the effect of mutation per generation is very small.
-When a population is in equilibrium for forward and reverse mutation rates, which of the following is true:
A) The number of forward muations is greater than the number of reverse mutations.
B) No forward or reverse mutations occur.
C) The number of forward mutations is equal to the number of reverse mutations.
D) The population is in Hardy-Weinberg equilibrium.

Question

Quizplus · Accepted Answer

At equilibrium, the rate of forward mutations is equal to the rate of reverse mutations, so the number of forward mutations equals the number of reverse mutations.
