A population of lizards with two common phenotypes for color is introduced into an environment. One phenotype is brown and the other is green. Throughout the year, the environment has a combination of green grassy areas and areas of brown soil without plants. Hawks and coyotes hunt the lizards for food. If the environment remains stable, what is likely to happen and why? A. The green phenotype is likely to become more common because green lizards will have less competition for resources. B. The brown phenotype is likely to become more common because brown lizards will be less likely to survive predation. C. Both phenotypes are likely to remain common because they will be equally likely to survive and reproduce. D. Both phenotypes are likely to become less common because they blend in with and can hide in their environment.
