How do rock pocket mice demonstrate natural selection?
Subsequent studies demonstrated that there is strong selective pressure maintaining Mc1r allele and coat colour frequencies across the short geographic distances between the light- and dark-coloured rock islands. Thus melanism in rock pocket mice is considered a fabulous example of adaptation by natural selection.Click to see full answer. Similarly, you may ask, what role does…
Subsequent studies demonstrated that there is strong selective pressure maintaining Mc1r allele and coat colour frequencies across the short geographic distances between the light- and dark-coloured rock islands. Thus melanism in rock pocket mice is considered a fabulous example of adaptation by natural selection.Click to see full answer. Similarly, you may ask, what role does the rock pocket mouse play in the food web?Mice are important as they feed small predators like snakes and foxes. They consume plants or producers and then are prey.One may also ask, what caused the dark variation in the rock pocket mice? One gene, called Mc1r, stimulates production of the black pigment in coat fibers. Nachman’s group made an educated guess that genetic differences in either the Mc1r or agouti genes might account for the dark pelage of rock pocket mice living in the volcanic areas. Herein, how does natural selection affect individual mice? Dark mice are better adapted to their environment and better able to survive and reproduce. Natural selection acting on mice population over time. Individuals have variations within their heritable traits. Some variations make an individual better suited to survive and reproduce in their environment.Where do pocket mice live?The five species of spiny pocket mice (genus Liomys) are found in extreme southern Texas, but they live mostly in Mexico southward to Panama in semiarid brushy and rocky habitats.
