Stabilizing Selection (also negative selection), a form of natural selection that is responsible for the preservation of the adaptive characteristics of organisms under constant environmental conditions. Stabilizing selection operates by means of the removal, or elimination, of individuals who deviate from the established norm.

stabilizing selection the tendency of natural selection to function so as to maintain the existing mean of a population characteristic (e.g., mean height, mean neck

1950.02910300087029. Stabilizing selection, also referred to as purifying selection, is a type of natural selection in which genetic diversity decreases as the population stabilizes on a Directional selection favours alleles that produce phenotypes at one extreme of a phenotypic range. Selection reduces variation at one extreme of the range while Stabilizing selection (left column) acts against phenotypes at both extremes of the distribution, favouring the multiplication of intermediate phenotypes. Directional Stabilizing selection around a fixed phenotypic optimum is expected to disfavor sexual reproduction, since asexually reproducing organisms can maintain a Stabilizing Selection.

Stabilizing Selection: The desert population of spiny cacti are under attack. Peccaries are eating those plants with low-spine-number causing their alleles to vanish from the gene pool and enriching the remaining gene pool in those alleles that create cacti with high-spine-numbers. stabilizing selection is not the norm. 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.

For example, the structure of the thyroid gland’s hormone —thyroxine—has remained unchanged throughout the evolution of vertebrate animals. 2019-09-20 · Azcolvin429 (Selection_Types_Chart.png) / GFDL.

I discuss six mechanisms by which plant-pollinator interactions could generate stabilizing selection on flowers. In addition, I consider the stabilizing roles of
