What is Genetic Variation?
Genetic diversity is the variation of heritable characteristics present in a population of the same species. It serves an important role in evolution by allowing a species to adapt to a new environment and to fight off parasites. It is applicable to domesticated species, which typically have low levels of genetic diversity. Studying genetic diversity in humans can help researchers form theories on human origins.
