Question

Suppose that, instead of a mouse with dark fur, a mouse with

white fur was born in the population of mice on the dark rock.

5a). What do you think would happen during the years after the white mouse appeared?

The white mouse would have offspring and would probably turn a lot of the population in the area turn white,

5b). Would you expect that white mice would become increasingly common in the population of mice on the dark rock? Explain why or why not.

Answer 1

5a. The gene for white fur in mice may be housed in the gene pool. The white mice would have offsprings and the frequency of the allele may increase.

5b. The white mice would not be increasingly common in the population of mice on the dark rock because they become easily noticeable for its predators since their color is contrasting to the background of the dark rock.

The mouse with dark fur would have a higher level of survival fitness compared to the mouse with white fur.

The population of white mice might decrease as the predatory rate increases, unless there is a sudden change in the color of the rock.
