Definitions:

Neutrally

In a manner that is unbiased, not favoring one side, or in genetics, referring to mutations that do not affect an organism's fitness.

Positive Selection

The evolutionary process by which alleles that confer a fitness advantage increase in frequency within a population, leading to adaptation.

Purifying Selection

A type of natural selection that removes deleterious alleles from a population, leading to a decrease in genetic variation for the traits affected.

Neutral Theory

A theory in molecular evolution that proposes most genetic variations are the result of genetic drift and not selective forces, and that at the molecular level, the majority of mutations are neutral.
