Changes in the frequencies of alleles within a population over time.

The process by which organisms with traits better suited to their environment survive and reproduce more successfully, passing on those advantageous traits.

The movement of alleles between populations due to migration.

The process by which mutations, genetic drift, gene flow, and natural selection alter the genetic makeup of a population.

Variations in the genetic makeup of individuals within a population.

The random changes in allele frequencies within a population, especially in small populations.

The mating pattern where individuals prefer to mate with others who have similar genotypes.

A type of assortative mating where individuals mate with the same genotype as their own, e.g., self-fertilization in plants.

A type of assortative mating where individuals mate with individuals with different genotypes.

The process of mating between closely related individuals, increasing the likelihood of homozygous genotypes.

The process of mating between unrelated individuals, decreasing the likelihood of homozygous genotypes.

A change in the DNA sequence of an organism.
