There appears to be fairly general acceptance of the idea that stabilizing selection is the cause of stasis. Even Gould, who may have been the most prominent champion of constraint hypotheses, recently acknowledged stabilizing selection based on niche tracking as a likely Directional selection, stabilizing selection and disruptive selection are three types of natural selection.They are also examples of adaptive evolution. Natural selection is the mechanism of evolution which favors organisms that are better adapted to their environments. Stabilizing selection is a type of selection which eliminates both extremes from an array of phenotypes while balancing selection is a number of selective processes that actively maintain multiple alleles of a gene in the gene pool of a population. Stabilizing Selection If natural selection favors an average phenotype, selecting against extreme variation, the population will undergo stabilizing selection (Figure 1). In a mouse population that live in the woods, for example, natural selection is likely to favor mice that best blend in with the forest floor and are less likely for predators 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 population’s genetic variance shifts toward a new phenotype when exposed to environmental changes.

An example of this is plant height. Stabilizing Selection Stabilizing selection favors the intermediate phenotype out of a range of phenotypes. The stabilizing effect is generated by a combination of asynchronous population fluctuations and overyielding (an increase in the temporal mean relative to the standard deviation).

Stabilizing selection is the exact opposite of disruptive selection, as it favors the intermediate form of a trait against the extreme forms. It causes a reduction in the variation observed in the expression of that trait and allows the propagation of the intermediate, most adapted trait in the population.

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 population’s genetic variance shifts toward a new phenotype when exposed to environmental changes. Stabilizing selection: Stabilizing selection occurs when the population stabilizes on a particular trait value and genetic diversity decreases.
