Nov 5, 2017 · Directional selection, stabilizing selection and disruptive selection are three types of natural selection. They are also examples of adaptive evolution.

Stabilizing selection results in a decrease of a population ‘s genetic variance when natural selection favors an average phenotype and selects against extreme variations. In directional selection, a …

Sep 20, 2019 · Directional selection happens when one extreme trait helps a species survive better in their environment. Disruptive selection favors both extremes of a trait, making the average trait less …

In Stabilizing Selection, individuals who deviate far from the ‘norm’ or average are selected against. An example of stabilizing selection can be explained by using the number of eggs found in a robin’s …

Phenotypes may also be subject to stabilizing selection or disruptive selection, which are both nonlinear forms of selection. The key distinction between stabilizing and disruptive selection is whether the …

4 days ago · This type of selection is common in stable environments where conditions do not change significantly. Directional Selection Directional selection favors phenotypes at one extreme of the trait …

Jan 3, 2026 · Differences Between Stabilizing, Directional, and Disruptive Selection Stabilizing Selection Definition: Favors the average phenotype and selects against extreme phenotypes. Effect: Reduces …

Explore the Types of Selection in Natural Selection for AP Biology. Understand directional, stabilizing, disruptive, and more with examples and key insights.

Nov 10, 2025 · Directional selection is visualized as the entire bell curve shifting to a new position, indicating a change in the average trait value. Stabilizing selection results in a taller, narrower curve …

This type of selection removes the individuals from one end towards the other end of phenotypic distribution. For example, size differences between male and female sparrows.
