Final answer:
The form of postmarital residence rule where couples move to the wife's community is known as matrilocal residence. This system is associated with matrilineal descent.
Step-by-step explanation:
Under the form of postmarital residence rule systems where couples move to the wife's community, the system is known as matrilocal residence. In this arrangement, after marriage, the couple establishes their new household with or near the bride's mother or the bride's mother's relatives. The husband thus leaves his parental home to join the wife in her community. Matrilocal residence is often associated with societies that trace their lineage and inherit through the mother's side, known as matrilineal descent.
