Which statement best describes homogamy's role in mate choice?

• A. It promotes cross-class, cross-group marriages.
• B. Homogamy reinforces marriage within similar social groups.
• C. It has no impact on social boundaries.
• D. It is solely about physical attraction.

Answer: (B)

Homogamy in mate choice describes the tendency to marry someone who shares similar social characteristics—such as class, education, religion, ethnicity, or cultural background. This similarity helps keep marriages within the same social group, which in turn reinforces social boundaries and the continuity of shared norms, resources, and networks. In other words, choosing a partner with similar background makes it easier to align expectations, lifestyles, and support systems, supporting the stability of existing social stratifications.

That’s why the statement that best describes homogamy’s role is that it reinforces marriage within similar social groups. It’s not about crossing class or group lines, it doesn’t render social boundaries irrelevant, and it isn’t solely about physical attraction—social similarity is the central driver.
