👉 In sociology, "exogamous" refers to relationships between people who have no direct line of descent from a common ancestor. This means that there are no shared ancestors or biological relations within the family unit. For example, in a traditional family, siblings would be considered exogamous, as they share a common parentage and lineage. In a non-traditional family structure, such as polygamy, where each spouse has multiple children with each partner, exogamous relationships may not exist
