​

Answer 1

Moiety system, also called dual organization, form of social organization characterized by the division of society into two complementary parts called “moieties.” Most often, moieties are groups that are exogamous, or outmarrying, that are of unilineal descent (tracing ancestry through either the male or female line, but not both), and that have complementary roles in society. For instance, members of the Raven and Wolf moieties in Tlingit culture traditionally performed certain tasks, such as preparing funerals, for each other. Moieties often reflect divisions found in the culture’s myths and folklore; the Tagaro and Supwe moieties of north Pentecost Island (Vanuatu), for instance, were named for two culture heroes and are said to bear the respective traits of each. Occasionally, if incorrectly, “moiety” is used more loosely to refer simply to one of two divisions of a society.
