WebNatural selection can cause a trait variation to become more or less common in a population over time. Natural selection requires variability, heritability, and reproductive advantage. Natural selection acts on random variations. Variations must pass from parent to offspring. 5 minutes.

Instead, drift changes allele frequencies purely by chance, as random subsets of individuals (and the gametes of those individuals) are sampled to produce the next generation.
