Sоmetimes twо оr more distinct phenotypes cаn eаch hаve their advantages for natural selection, while the intermediate phenotypes are, on average, less fit. Imagine a mouse population living at the beach where there is light-colored sand interspersed with patches of tall grass. In this scenario, light-colored mice that blend in with the sand would be favored, as well as dark-colored mice that can hide in the grass. Medium-colored mice, alternatively would not blend in with either the grass or the sand, and thus predators would most likely eat them. This is an example of ________________.
