Which type of selection favors extreme traits?
Directional selection
Directional selection occurs when selection pressures favor one extreme of the trait distribution. Selection is disruptive when the average form of the trait is selected against while either extreme is unaffected. Natural selection can take many forms.
What is the type of selection that favors selecting one extreme form within a population called?
Diversifying (or disruptive) selection: Diversifying selection occurs when extreme values for a trait are favored over the intermediate values.
Which type of selection Favours the phenotypes at one extreme over the other?
Stabilizing selection
Stabilizing selection When individuals with intermediate phenotypes are favoured and extreme phenotypes are selected against, the selection is said to be stabilizing.
What type of selection favors the average?
Stabilizing selection is a type of natural selection that favors the average individuals in a population. This process selects against the extreme phenotypes and instead favors the majority of the population that is well adapted to the environment.
What are three types of natural selection?
The 3 Types of Natural Selection
- Stabilizing Selection.
- Directional Selection.
- Disruptive Selection.
What are three examples of natural selection?
Deer Mouse.
What are three types of selection?
Which type of selection is most common?
stabilizing selection
The most common of the types of natural selection is stabilizing selection. In stabilizing selection, the median phenotype is the one selected for during natural selection.

What is a good example of Intrasexual selection?
Intrasexual selection, on the other hand, occurs between members of the same sex. For example, male sea lions compete for dominance over rookeries of females. Here, intrasexual selection acts on the physiology of the sea lion, to make it large enough to compete with other males for a group of females.
What is the most common type of natural selection?
Stabilizing selection Stabilising selection is probably the most common type of natural selection; it favours the most common phenotype as the best adapted. Stabilising selection reduces variation by selecting against alleles that produce more extreme phenotypes at either end of the phenotypic range.
