Detailed explanation-1: -Stabilizing selection selects against individuals with extreme traits and favors individuals with average traits. Stabilizing selection drives the population towards average traits.
Detailed explanation-2: -Stabilizing selection (not to be confused with negative or purifying selection) is a type of natural selection in which the population mean stabilizes on a particular non-extreme trait value.
Detailed explanation-3: -Stabilizing Selection When selective pressures select against the two extremes of a trait, the population experiences stabilizing selection. For example, plant height might be acted on by stabilizing selection. A plant that is too short may not be able to compete with other plants for sunlight.
Detailed explanation-4: -Disruptive selection: Both extreme phenotypes have a higher fitness than intermediate phenotypes.
