Quick Summary

Ambilateral descent is a kinship system where both patrilineal and matrilineal principles operate. However, individuals have some choice in defining their connection to either their mother's or father's group. In some ambilateral systems, marriage can expand one's lineage choices to include in-laws. This contrasts with unilineal systems, which emphasize ties through only one parent, and bilateral systems, which recognize kinship through both parents equally. Kinship systems are crucial for establishing social parentage, influencing rights, duties, and inheritance.12
