Definitions:

Selection

The process by which certain traits become more or less common in a population due to their impact on the reproductive success of their bearers.

Directional Selection

A form of natural selection in which individuals with traits on one end of the spectrum are more likely to survive and reproduce, leading to an overall shift in the population.

Stabilizing Selection

An evolutionary process that favors the average variants in a population, leading to a decrease in diversity for the trait in question.

Disruptive Selection

Disruptive selection favors individuals at the tails of the distribution of phenotypes present in a population (for example, by acting against individuals with intermediate trait values).
