Researchers have undertaken a long-term study of populations of rock pocket mice,
Chaetodipus intermedius, in Arizona and New Mexico. Rock pocket mouse fur is either dark or
light in color. Most of the populations studied live in areas with light-colored granite rocks;
however, some areas are dominated by dark-colored rocks from ancient lava flows.
Researchers collected mice from six sites in Arizona and recorded their coat colors. Figure 1
shows the study sites, the rock colors, and the distribution of coat colors. In the Arizona
populations, the melanocortin-1 receptor (MC1R) gene is responsible for coat color phenotype
(light or dark). The MC1RD allele, which results in a dark coat, is dominant to the d allele.
Researchers collected samples of mice from all six study sites and sequenced the MC1R gene.
They also collected mice with dark coats from a location in New Mexico, the Carrizozo lava flow,
to determine if t - Answer✔Dark color is selected for in mice from the West, Mid, and East
populations.

rocks; therefore, mice with dark coats have a lower predation rate in that habitat.
