- A mating system characterized by the inter-breeding of genetically unrelated or dissimilar individuals. Since genetic diversity tends to be enhanced, and vigour or fitness of individuals increased by this process, it is often used to counter the detrimental effects of continuous inbreeding. Synonym: exogamy.
