Stabilizing selection and the comparative analysis of adaptation. TF Hansen Comparing strengths of directional selection: how strong is strong? J Hereford, TF

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

One purpose of this article is to ﬁll this gap, by developing analytical approximations for the parameters of interest, using a method originally developed by Kimura (1981), which is related to that used in models of Purifying / stabilizing selection is not the sole cause of stasis. The reason can be that methods for detecting stabilizing selection are complex.; Inheritance alone is too imperfect to achieve a purifying and stabilizing selection.; Stabilizing selection is the opposite of disruptive selection.; For example, long-term stabilizing selection related to stable environments might cause stasis. Directional Selection. The first type of natural selection is called directional selection.

Stabilizing selection

For example, the coats of Stabilizing selection is any selective force or forces which push a population toward the average, or median trait. Stabilizing selection is a descriptive term for what happens to an individual trait when the extremes of the trait are selected against. Stabilizing Selection: Examples And Definition Types Of Natural Selection. Natural selection is the process by which evolution occurs, making a species evolve into a Key Points About Stabilizing Selection.

stabilizing selection o the average phenotype is most adaptive. o mode is stable o curve may become more narrow. • directional selection o phenotype at one 29 Aug 2014 Nourmohammad, A., Schiffels, S. & Lässig, M. Evolution of molecular phenotypes under stabilizing selection.

2009-11-03 · Stabilizing selection commonly uses negative selection (a.k.a. purifying selection) to select against extreme values of the character. A good classic example of this is human birth weight. Babies of low weight lose heat more quickly and get ill from infectious disease more easily, whereas babies of large body weight are more difficult to deliver through the pelvis.

dominance (nonadditive within locus). b. epistasis (nonadditive between loci). 3. stabilizing selection.

Stabilizing selection: Stabilizing selection occurs when the population stabilizes on a particular trait value and genetic diversity decreases. Stabilizing selection is a type of natural selection that favours the average individuals in a population. In other words, stabilizing selection pushes a population towards the average or median while eliminating the two extreme phenotypes. The environment normally favours the average phenotype within the population.

stabilizing selection is not the norm. There appears to be fairly general acceptance of the idea that stabilizing selection is the cause of stasis.

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.

This does not skew the bell curve in any way. 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 in evolution is a type of natural selection that favors the average individuals in a population.
