The diagram shown illustrates the change that occured in the frequency of phenotypes in an insect population over 10 generations. The spotted
insects of the species shown look similar to a poisonous beetle also
found the area.
A probable explanation for this change would be that over time there
was...
A. an increase in the population overall due to this being unfavorable
b. an increase in the recessive allele due to this trait being favorable
c. an increase in the heterozygous individuals due to this trait being favorable
d. an increase in the dominant allele due this trait being unfavorable
