The area in which a population of white and brown mice live has started getting much more snow than it

has in the past. If this trend continues, what would you expect to happen to the alleles that code for

white and brown fur?

-The allele for brown fur would probably increase as genetic drift works on the population.

-The allele for white fur would probably increase as genetic drift works on the population.

-The allele for brown fur would probably increase as natural selection works on the population.

-The allele for white fur would probably increase as natural selection works on the population.

    The allele for white fur would probably increase as natural selection works on the population.

    Explanation:

    The white mice are well adapted to survive in cold winter months and snowfall, where they can easily hide to avoid predation. The brown mice in are more suited to the autumn, spring and summer; the trees lose their leaves before cold seasons.

    Tree litter and leaves will offer great protection for brown mice in warmer months. Camouflage is a defensive adaptation to avoid predation; to avoid detection, the rabbits mix in natural colors, shapes, and patterns. At the beginning of longer winters, brown mice will not be able to avoid wolves by playing in snow; they would stand out, while white mice would blend in, in comparison to their surroundings.
