Which factor is NOT typically associated with kinship structures?

Kinship structures encompass the social relationships formed through blood ties, marriage, and other forms of legal or social connections. Typically, these structures are influenced by biological ties, such as genetic relationships, and legal bonds that formalize relationships through marriage or adoption. Shared roles among family members are also a critical component, as these can dictate responsibilities, inheritance, and care dynamics within a kinship group.

Societal expectations, while they can influence how kinship structures are perceived or function in practice, do not form an inherent part of kinship structures themselves. These expectations may vary widely across different cultures and can lead to diverse interpretations of kinship. However, they are not a defining characteristic of kinship as they are more external and socially constructed, rather than fundamental to the concept of kinship itself. Thus, the option reflecting societal expectations is not typically associated with kinship structures directly.
