1) What are common patterns of distribution related to rock pocket mice coat color?
The patterns of distribution related to rock pocket mice coat color is primarily focused on the genetic variation regarding the fur color of the mice. The population of mice that possess a lighter fur color typically live in regions that contain light coloured rocks within the environment. Still, mice that have a darkened color fur will most often be found in areas in which the environment is surrounded by volcanos with lava flow. The common pattern of the coat color between the rock pocket mice show a correlation with the terrain color, in which there is an adaptive mechanism against predators, which increases the chances of survival. …show more content…
It causes the pigments in populations to darken in color within darken surroundings. In this case, adaptive melanism improves their ability for camouflage, which makes them less noticeable to predators.
2 4) What were the genotype-phenotype associations between Mclr alleles and coat color in rock pocket mice from the Pinacote study site?
1 The mc1r allele is a protein that correlates to pigment of the rock pocket mice from the Pinacote study site, which is a phenotype related to melanism.
5) Why would a rock pocket mouse’s color influence its overall fitness?
The color influences its overall fitness due to the fact that fur color plays a major role within the population and its overall ability to eventually reproduce and form a population. On light backgrounds, light colored pocket-mice have an advantage over dark colored pocket-mice. However, on the black rocks, dark mice possess an advantage over light mice, making the light colored mice attracted to predators. In both situations, the fur color of these two types of pocket mice helps to protect themselves against predators that look for the mice that does not match the substrate. Its color influence can increase or decrease its overall fitness in a particular environment. Depending on the color of the mice, it determines its chances of survival and to reproduce, passing their colored fur genes (favoured alleles) to their offspring and continue to form
