Final answer:
An extended family consists of more than two generations of a kinship line living together, which includes multiple family units operating as a single unit with shared rights and responsibilities.
Step-by-step explanation:
When more than two generations of the same kinship line live together, either in the same dwelling or in adjacent dwellings, the group is called an extended family.
An extended family includes two or more family units functioning as a single, integrated family and may involve multiple generations.
This familial arrangement provides mutual support and maintains kinship ties, with members having distinct rights and responsibilities within the family unit.
Common in various societies, extended families can have sociopolitical impact and carry on lineage and cultural traditions.
