25 If the all the white mice are selected against in this environment (eaten by predators) what would happen to the gray mice if the environment were to change quickly to favor white mice? A. B. C. The gray mice would all change to white fur quickly and survive because the genetic traits are recessive and therefore still available in the population's genetics. The gray mice would immediately be eaten by the predators in the area and go extinct. The gray mice could still give birth to white mice if the trait remained in their genetic information and the population could produce white fur offspring which over time would succeed and reproduce causing an increase in white mice. The gray mice would have to move and white mice would move into the area causing the two to quickly develop different genetic traits and to evolve into entirely separate species until the two are no longer the same population. D.

Natural selection is the differential survival of some members of the population of species which have better phenotypic advantage over others. Such members will survive and reproduce. According to the given situation, white mice were the choice of food for predators and the recessive trait of gray color of gray mice was favoring their survival as they may remain undetected by the predators. But the predators were able to detect the gray mice and changed their food preference from white to gray this way predators will consume all the gray mice and they may extinct in future as it is not possible to change the color of the fur from white to gray so quickly. The adaptation and passage of white trait among the members of the population will occur with a gradual change in successive generations of the population.
