c. maintain two or more phenotypes in a population.

Male common side-blotched lizards have different colors and are characterized by different reproductive strategies. An increase in the frequency of any males induces the increase in the frequency of males of other colors. For example, due to specific patterns of reproductive behavior, when a population contains a high number of blue males, orange males are favored by natural selection. The population with blue males will increase when there is a high number of yellow males. Finally, the frequency of yellow males will increase when orange males are the most populous. This strategy helps to maintain all three male phenotypes in a population.
