The document describes three types of natural selection: stabilizing selection, which favors intermediate phenotypes; directional selection, where the distribution shifts towards a single extreme phenotype; and disruptive selection, which eliminates intermediate phenotypes in favor of extremes.

1. Three types of natural selection Classify each description according to the type of natural
selection it describes.
Solution
Stabilizing selection
Natural selection favors intermediate phenotypes over the extreme phenotypes
Selection act to eliminate one extreme from an array of phenotypes
Directional selection
The distribution curve shifts in the direction of single extreme phenotype
Selects for a midsized body for example
Disruptive selection
Selection act to eliminate the intermediate phenotype
Natural selection favors extreme phenotypes over the intermediate phenotypes
