Suppose you are studying a recently discovered population of rock pocket mice with dark-colored fur that lives on volcanic rock. You take a DNA sample from a member of this new population and determine the DNA sequence of a gene known to play a role in fur color. When the normal Mc1r gene is present, melanocytes, which are melanin-producing skin cells, decrease the production of the dark-colored pigment called eumelanin and increase the production of the light-colored pigment, pheomelanin.
