In social studies, exogamy is viewed as a combination of two related aspects: biological and cultural.
Biological exogamy is marriage of non blood-related beings, regulated by forms of incest law. A form of exogamy is a dual exogamy, in which two groups engage in continual wife exchange.
Cultural exogamy is the marrying outside of a specific cultural group.
The opposite of exogamy is endogamy, a marriage within a social group.
