Rocket pocket mouse answer key6/23/2023 Record your counts in the spaces provided at the top of each illustration. Count the number of light-colored and dark-colored mice present at each location at each moment in time. Each full-page illustration shows the color variation at two different locations, A and B, at a particular moment in time. It is sometimes grouped in the genus Perognathus.2 Description Found mainly in rocky outcrops in the deserts of the southwestern United States and Mexico, the rock pocket mouse is medium-sized (length 18 à Âcm, weight 12¢Ã  Â18g) and nocturnal. What macromolecule determines whether a rock pocket mouse will inherit light-colored fur or dark-colored fur? Insert Answer Due to natural selection, which color variety of mouse-dark or light-would you expect to be most common where there were lave flows? Insert Answer Which mouse variety would you expect to be most common where there were not lava flows? Insert Answer Part 1: Collecting data The illustrations on the following pages represent snapshots of rock pocket mouse populations. pocket mice is considered a fabulous example of adaptation by natural selection. Most of the landscape consists of light- colored sand and rock, but patches of dark volcanic rocks that formed from cooling lava flows are found, separated by several kilometers of light-colored substrate. There are also two major colors of substrate, or surface materials that make up the desert floor. There are two common varieties-a light-colored variety and a dark-colored variety.
