disruptive selection
Stabilizing selection is a type of natural selection that favors the intermediate phenotypes in a population, leading to a decrease in genetic diversity. Disruptive selection, on the other hand, favors extreme phenotypes over intermediate ones, resulting in increased genetic variation within a population.
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.
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.
In an unchanging environment, selection in a well-adapted population is stabilizing selection. This type of selection favors individuals with intermediate phenotypes, maintaining the status quo of the population's genetic characteristics.
disruptive selection
When natural selection favors the intermediate version of a characteristic, it is referred to as stabilizing selection. It is the opposite of disruptive selection.
Stabilizing selection is a type of natural selection that favors the intermediate phenotypes in a population, leading to a decrease in genetic diversity. Disruptive selection, on the other hand, favors extreme phenotypes over intermediate ones, resulting in increased genetic variation within a population.
Stabilizing selection is the type of selection that keeps the center of the curve at its current position. This type of selection removes extreme phenotypes from the population, favoring the intermediate phenotype.
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.
Disruptive selection occurs when the extreme phenotypes in a population are favored over intermediate phenotypes. This can lead to the divergence of a population into two distinct groups with different traits.
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.
Stabilizing selection is the mode of selection that can lead to a reduction in variation without changing the mean of a trait. In this type of selection, extreme phenotypes are selected against, while intermediate phenotypes are favored, resulting in a narrower range of phenotypic variation but maintaining the same mean.
Stabilizing selection, which acts against both extreme phenotypes and favors intermediate variants. Hence the narrowing of the bell curve in the middle.
In an unchanging environment, selection in a well-adapted population is stabilizing selection. This type of selection favors individuals with intermediate phenotypes, maintaining the status quo of the population's genetic characteristics.
