Artificial selection.
The most common type of natural selection is stabilizing selection. This type of selection favors average traits in a population, reducing genetic diversity and maintaining the status quo of a population's characteristics.
Stabilizing selection is the type of natural selection that acts against extreme forms of a polygenic trait to reduce genetic variation and maintains the average value of the trait within a population. It favors the intermediate phenotype, leading to a narrowing of the range of variation for that trait over time.
Yes, the shift in body weight towards an intermediate range in sociable weaver birds can be an example of stabilizing selection. This type of selection favors individuals with traits closest to the average or intermediate value in the population, reducing extremes in the phenotypic variation.
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.
Artificial selection.
Natural Selection.
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.

Sexual selection is a type of natural selection resulting from variation in the ability to obtain mates.
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.
Gene flow that involves the movement of individuals from a high-variation population into a low-variation population can result in a reduction of genetic variation. This can happen if the incoming individuals do not introduce new alleles or if genetic drift and selection reduce the frequency of existing alleles.
Disruptive selection is a type of natural selection that favors extreme traits over the average trait, leading to the divergence of characteristics within a population. This process can result in the formation of two distinct phenotypic groups with reduced variation between them.
This type of selection is called artificial selection.
There are infinitely many types of variation.
