What does homogamous mean?
Homogamous describes marriage or mating that occurs within a defined category rather than across categories. In anthropology and sociology, the category may be based on religion, ethnicity, class, kinship, or another social boundary; such pairing can help preserve group identity and reinforce social divisions. In biology, homogamous reproduction involves individuals who are genetically similar, potentially increasing the likelihood that offspring will inherit similarities shared by their parents. The word is formal and specialized rather than everyday, and its precise meaning depends on the discipline using it. Its principal contrast is with exogamous, which refers to marriage or mating across social or genetic boundaries. Homogamous should not be confused with homogeneous, a broader word meaning composed of similar or identical elements.
