Question
what is disruptive selection?
selection that favors both extremes over intermediate forms
stabilizing the population size of an organism within a certain area
the removal of all traits from an organisms gene pool
selecting only the most common trait among similar species
Disruptive selection is a type of natural selection. In this process, extreme phenotypes are favored over intermediate phenotypes. This leads to the population being divided into two distinct groups. For example, if there is a population of birds with beak sizes, and in their environment, small - beaked birds can easily eat small seeds and large - beaked birds can eat large seeds, but intermediate - beaked birds struggle with both. Then, over time, the number of small - beaked and large - beaked birds will increase, while the number of intermediate - beaked birds will decrease.
