Final answer:
Kinship is based on three factors: lineal kinship, bifurcate merging kinship, and generational kinship. These structures determine relationships, roles, and obligations within a family and community.
Step-by-step explanation:
Kinship is a web of relationships in which people consider themselves related to each other in a social and biological way. It is based on three factors: lineal kinship, which focuses on the nuclear family; bifurcate merging kinship, which distinguishes between parallel and cross cousins; and generational kinship, which includes all kindred within the same generation. These different kinship structures help to determine rights, obligations, and roles within a family and community.
