Directional stabilizing and disruptive
WebStabilizing selection reduces the amount of variation in a trait. Disruptive selection increases the amount of variation in a trait. Stabilizing selection selects against extreme individuals.

Disruptive selection favors both extreme phenotypes, different from one extreme in directional selection. Stabilizing selection favors the middle phenotype, causing the decline in variation in a population over time.
