Genetic differentiation occurs when populations of the same species develop differences in their genetic composition. Learn how gene flow, genetic drift, natural selection, and isolation shape these differences.

Natural selection is a key mechanism of evolution in which heritable differences in survival and reproduction cause changes in populations over generations.

Population genetics is the study of genetic variation within and among populations and how allele frequencies change over generations through mutation, recombination, selection, genetic drift, gene flow, population history, and breeding. In domestic animals, population genetics provides the foundation for understanding breed development, genetic diversity, population structure, adaptation, animal breeding, and conservation.
