2. A rock pocket mouse’s color influences whether it survives or dies. The less visible the mouse is in its habitat, the more likely it will survive. Mice that stand out in their habitat have a greater chance of being spotted by a predator. Mice that are similar in color to their habitat are more likely to survive and reproduce.
3. A mutation in the DNA of rock pocket mouse in location A caused it to have black fur. Because the dark-colored fur was easily visible on the light-colored surface of location A, the dark-colored mice were more easily spotted by predators than the light-colored mice. This phenotype did not become more common since more of the dark-colored mice were not able to survive and reproduce.
