Final answer:
Regina's society follows a patrilineal descent system, where children are related only to their father's relatives, and lineage is traced through the male line, which can lead to a patriarchal society structure.
Step-by-step explanation:
Regina lives in a society where children are related to their father's relatives but not their mother's relatives, illustrating a patrilineal descent system. In such systems, lineage, inheritance, and familial affiliations are traced exclusively through the male line. This means only males carry on the family surname, granting them the prestige of permanent family membership. In contrast, females are often seen as only temporary members of the family, which can be observed in societies with strong patrilineal and patrilocal residence traditions.
In a broader context, there are other types of kinship systems, such as matrilineal descent, where the lineage is traced through the female line, and ambilineal descent, where families may choose to trace lineage through either the mother's or the father's side. It is worth noting that while patrilineal societies tend to be patriarchal, societies with matrilineal descent are not necessarily matriarchal, and the decision of residence upon marriage can be influenced by the type of descent system in place.
