Rock Pocket Mouse

Where do rock pocket mice live geographically?

• Northwestern U.S.
• Southwestern U.S.
• Southeastern U.S.
• Northeastern U.S.

Which of the following is TRUE? Read carefully.

• Most mice have sandy, light-colored coat to match the environment where they live.
• Most mice have dark colored fur to match the environment where they live like their ancestors.
• Most mice contrast with their environment.
• Most mice are heterozygous for fur color and therefore display both phenotypes.

Why did the MCr1 gene mutation become prevalent in the rock pocket mouse populations?

• The mutation produced dark colored mice who were better able to survive and reproduce in basalt environments.
• The mutation produced light colored mice who were better able to survive and reproduce in basalt environments.

The  MCr1 mutation across a variety of species shows that

• evolution is by design.
• evolution of melanism is a repeatable process.
• new mutations of melanism comes from a common ancestor.
• evolution of melanism is random.

For the rock pocket mouse, which of the following contributes to selective pressure favoring dark-colored fur? (Choose all that apply)

• Predators

• Genetic mutations

The Rock Pocket mice move to the environment that matches their fur.

• True

• False

NGSS.MS-LS4-4

Dark mice are more likely to survive in the dark rocks because the predators cannot see them as easily.

• True

• False
