The change in allele frequencies in a population over time.

The process where organisms better adapted to their environment tend to survive and reproduce.

A localized group of organisms belonging to the same species.

The total collection of genes in a population at a given time.

States allele frequencies in a gene pool remain constant unless acted upon by influences.

A change in allele or genotype frequencies within a population.

Differences in heritable traits that are essential for evolution.

Five criteria required for a population to be in Hardy-Weinberg equilibrium.

A rare change in DNA that generates genetic variation.

An individual's contribution to the gene pool compared to others.

Selection favoring individuals at one extreme of a trait range.

Selection favoring individuals at both extremes of a trait range.

Selection favoring intermediate variants over extremes.

Matching organisms' traits better to their environment over time.

Random changes in allele frequencies in a population.

Mating that doesn't occur by chance, increasing homozygous loci.

Mating between close neighbors in a population.

Mating with partners that share similar phenotypes.

Drastic reduction in population size impacting allele representation.

Genetic drift occurring when a few individuals establish a new population.

Transfer of alleles between populations via migrating individuals.
