Shortly after a stream dried up, you noticed a change in the field mouse population coat color variation. When the stream was flowing, there were two populations, one with darker coats and one with lighter coats. After the stream dried up, mice with darker coats were being born into the lighter coat population and vice versa. a. True
b. False

a. True

Explanation:

When the stream dried up darker coat mice were seen into the lighter coat population and vice versa because of the natural selection process.

Mice change their coat color by adapting the changes in the stream flow and evolve their coat either dark or light that provides camouflage so predators won’t see them and they are able to survive in the environment. Mice have the advantage of surviving long and they are able to pass their genes to the offspring.

Hence, the given statement is true.
