  16. The diagram above illustrates the change that occurred in the frequency of phenotypes in an insect population over 10 generations. A probable explanation for this change would be that over time there was A. a decrease in the adaptive value of gene a B. an increase in the adaptive value of gene a C. an increase in the population of this insect D. a decrease in the mutation rate of gene A
