Imagine a population of rabbits with fur color that ranges from black to white. If this population were put in an area that has dark rocks that camouflage the black rabbits, as well as light stones that hide the white rabbits, what would most likely happen to the gray rabbits? Gray rabbits would blend into either environment.
Gray rabbits would adapt to have black fur.
Gray rabbits would be eliminated by predators.
Gray rabbits would mutate their genes.
