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.
The most common phenotype in a natural population is typically referred to as the wild type. This refers to the phenotype that is most prevalent and often considered the standard or original form of the trait in that population.

The most common form of a gene in a population is known as the wild-type allele. It is considered the standard form due to its prevalence in natural populations.
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.
If a population exists in an environment that changes very little, then natural selection may not provide any pressure to change. However, even under these conditions genetic driftoccurs, introducing random change within the parameters set by natural selection.
Natural Selection
Natural selection directs evolution; it cannot stop or prevent it.
Natural Selection.
It is stabilizing 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.
This type of natural selection is called stabilizing selection because the mean traits of the population are being selected for against the immediate environment.
The phenotype that is present in most individuals in nature is typically the wild type phenotype, which is the most common and often the ancestral form of a trait within a population. It is favored by natural selection due to its adaptability and overall fitness for survival in the environment.
The most common phenotype in a natural population is typically referred to as the wild type. This refers to the phenotype that is most prevalent and often considered the standard or original form of the trait in that population.
In Darwin's time, it would be classified as "natural" selection.
Directional selection.
This is called, sexual selection.
Reproductive isolation through sexual selection is often an important factor in speciation. This type of natural selection can lead to the evolution of reproductive barriers that prevent individuals from different populations from successfully interbreeding, ultimately resulting in the formation of distinct species.
