GGG and GGC are codons for the amino acid, glycine. A mutation caused the insertion of a cytosine in place of the guanine during DNA replication. Over many generations the DNA changes so that the frequency of GGC is similar to that of GGG. What effect does this mutation have on the population's mean fitness?



A. As the frequency of the GGC codon increases, the population's mean fitness level will remain the same.
B. As the frequency of the GGC codon increases, the population's mean fitness level will initially increase, but once GGC and GGG occur with equal frequency, the mean fitness will decrease.
C. As the frequency of the GGC codon increases, the population's mean fitness level will decrease.
D. As the frequency of the GGC codon increases, the population's mean fitness level will increase.
