Q.
The given diagram 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
A) Over time there was a decrease in the adaptive value of gene a
B) Over time there was an increase in the adaptive value of gene a
C) Over time there was an increase in the population of AA, Aa
D) Over time there was an decrease in the mutation rate of gene a
Explanation
Population genetics shows us that certain traits of a species becomes more abundant if they benefit the species. In this case, plant must have camouflage the insects, for having spots therefore, the gene ‘a’ responsible for the spotting increased over the time in the population
