Stabilizing Selection Stabilizing selection can be thought of as "middle-of-the-road" selection, meaning a non-extreme trait is favored instead of one of the two extreme traits. An example of this is plant height. Stabilizing Selection Stabilizing selection favors the intermediate phenotype out of a range of phenotypes.

Stabilizing, directional and disruptive selection - YouTube. Queen nerdling describes stabilizing, directional and disruptive selection. stabilizing selection a type of SELECTION in which both extremes of a phenotypic range are selected against, producing a stable The mean represents the stable average phenotype. Collins Dictionary of Biology, 3rd ed. © W. G. Hale, V. A. Saunders, J. P. Margham 2005 Want to thank TFD for its existence? 2015-01-13 Traits undergo stabilizing selection when individuals expressing intermediate phenotypes have the highest relative fitness.: When population geneticists think of stasis at all, they usually regard it as an almost trivial consequence of stabilizing selection.: Stabilizing selection is the most frequent form of selection found for quantitative characters in populations in stable habitats.

Stabilizing selection happens when extreme phenotypes on both ends of the spectrum are unfavorable. It's easier to understand stabilizing selection by looking at a visual representation. Here's a Stabilizing, directional and disruptive selection - YouTube. Queen nerdling describes stabilizing, directional and disruptive selection. Stabilizing selection is one of three main types of natural selection in evolution. The others are directional and diversifying selection.

Stabilizing selection is the opposite of disruptive selection. Instead of favoring individuals with extreme phenotypes, it favors the intermediate variants. Stabilizing

The distribution of VN within subpopulations seems to be under the influence of stabilizing selection. Differences among subpopulations might instead reflect 

Stabilizing selection When selective pressures select against the two extremes of a trait, the population experiences stabilizing selection. For example, plant height might be acted on by stabilizing selection. A plant that is too short may not be able to compete with other plants for sunlight.

Stabilizing selection

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. It is one of five types of selection processes used in evolution: The others are directional selection (which decreases the genetic variation), diversifying or disruptive selection (which shifts genetic variation to adjust to environmental changes), sexual selection (which If there is stabilizing selection pressure, the curve should be narrower, but with the same mean.

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.
