Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Pattern of natural selection that results in the extremes being suppressed and the intermediate being favored.
A
directional selection
B
disruptive selection
C
stabilizing selection
D
balancing selection
Explanation: 

Detailed explanation-1: -This type of natural selection occurs when selective pressures are working in favour of the two extremes and against the intermediate trait. This type of selection is not as common.

Detailed explanation-2: -The only choice that would favour intermediate phenotypes of a species over extreme phenotypes within a particular population is stabilizing selection. Stabilizing selection will select against extreme phenotypes of a particular species.

Detailed explanation-3: -Diversifying (or disruptive) selection: Diversifying selection occurs when extreme values for a trait are favored over the intermediate values. This type of selection often drives speciation.

Detailed explanation-4: -When individuals with intermediate phenotypes are favoured and extreme phenotypes are selected against, the selection is said to be stabilizing.
