This section discusses how genetic changes (mutations and recombinations) serve as the raw material for natural selection.

Sudden, stable changes in the genotype that can be beneficial, harmful, or neutral. This section discusses how genetic changes (mutations and

Favors phenotypes at one extreme, leading to a shift in traits when environmental conditions change. This section discusses how genetic changes (mutations and

The result of genetic material mixing during sexual reproduction (meiosis and fertilization). This section discusses how genetic changes (mutations and

Favors individuals at both extremes of a trait distribution, potentially leading to the formation of two distinct groups.

Favors average phenotypes and preserves established traits in stable environments.
