11 Members Description This animation shows why different fur colors can be advantageous to mice in different environments. Rock pocket mice can have either light-colored or dark-colored fur. As shown in the animation, mice that blend in with their surroundings are harder for owls and other predators to see.

1. The four illustrations provided by your teacher represent snapshots of rock pocket mouse populations. Each illustration shows the color variation at two different locations, A and B, at a particular moment in time. The illustrations may be out of order. Count the number of light-colored and dark-colored mice present at each location at each.
