Arctic foxes typically have a white coat in the winter. In summer, when there is no snow on the ground, the foxes typically have a darker coat. Which of the following is most likely responsible for the seasonal change in coat color? Show (A) The decrease in the amount of daylight in winter causes a change in gene expression, which results in the foxes growing a lighter- appearing coat. (B) The diet of the foxes in summer lacks a particular nutrient, which causes the foxes to lose their white coat and grow a darker- colored coat. (C) Competition for mates in the spring causes each fox to increase its camouflage with the environment by producing a darker- appearing coat. (D) The lower temperatures in winter denature the pigment molecules in the arctic fox coat, causing the coat to become lighter in color. Why do arctic foxes change color biology?(D) The lower temperatures in winter denature the pigment molecules in the arctic fox coat, causing the coat to become lighter in color.

How do mutations lead to genetic variation?Mutation Generates New Alleles
Mutation creates slightly different versions of the same genes, called alleles. These small differences in DNA sequence make every individual unique. They account for the variation we see in human hair color, skin color, height, shape, behavior, and susceptibility to disease.
