Tan fur helps the mice protect themselves from predators
Explanation:
The entrenchment of this phenotype in the population is powered by natural selection pressures. The mice with fur color that enable them to camouflage with their environment are predated less than mice with other fur colors. These tan mice are therefore more likely to survive and pass their genes to the next generation. Through successive generations, the allelic frequency for the tan fur color increases until it is the dominant allele in the population.
