Question

-How would you describe the gene changes shown in this figure?
A) No genes have changed, since all flies have a gene for alcohol processing. 
B) The number of genes in the population has increased. 
C) The frequency of the fast enzyme allele has decreased. 
D) The frequency of the fast enzyme allele has increased.

Accepted Answer

The description suggests that there has been a change in the allele frequency within the population, specifically an increase in the frequency of the fast enzyme allele. This indicates that more individuals in the population now carry the allele for the fast-processing enzyme, which is a key aspect of evolution and genetic variation.
