A type of natural selection in which genetic diversity decreases as the population stabilizes on a particular trait value.
The three patterns of natural selection are directional selection, stabilizing selection, and disruptive selection. Directional selection favors individuals at one extreme of a trait distribution, stabilizing selection favors the intermediate phenotype, and disruptive selection favors individuals at both extremes of a trait distribution.
disruptive selection
They both decrease genetic variation
Disruptive selection produces a distribution of phenotypes opposite to that of stabilizing selection. While stabilizing selection favors intermediate phenotypes and reduces variation, disruptive selection favors extreme phenotypes at both ends of the spectrum, leading to increased variation within a population. This can result in two or more distinct forms, promoting speciation over time.
Disruptive selection produces a distribution of phenotypes that is opposite to that of stabilizing selection. While stabilizing selection favors intermediate phenotypes and reduces variation, disruptive selection favors extreme phenotypes at both ends of the spectrum, leading to increased variation within a population. This can result in the emergence of two distinct phenotypic groups, potentially leading to speciation over time.
When natural selection favors the intermediate version of a characteristic, it is referred to as stabilizing selection. It is the opposite of disruptive selection.
