The three kin naming systems named after North American Indian cultures.

The general kinship term for a cousin who is ego's father's brother's children or mother's sister's children. (Hint: the gender of the cousin is not relevant in making this distinction.)

The general kinship term for a cousin who is ego's father's sister's children or mother's brother's children. (Hint: the gender of the cousin is not relevant in making this distinction.)

The cousins who would be considered relatives in a society with unilineal descent. (Hint: think in terms of cross and parallel cousins. The answer will be the same for patrilineal and matrilineal descent.)

The descent pattern of societies that use the Omaha kin naming system. (Hint: think in terms of patrilineal, matrilineal, bilateral, etc.)

The descent pattern of societies that use the Crow kin naming system. (Hint: think in terms of patrilineal, matrilineal, bilateral, etc.)

The kin naming system that is almost a mirror of the Omaha system. (Hint: in both systems, siblings and parallel cousins of the same gender are given the same term of reference, and other relatives not in ego's unilineage are lumped across generations in regards to kin terms.)

The kin naming system in which the same term of reference is used for father and father's brother as well as mother and mother's sister. (Hint: this merging is related to shared membership in unilineages, as it is in the Omaha and Crow systems. However, this system may be either patrilineal or matrilineal and is usually not as strongly one or the other.)

The kin naming system in which siblings and parallel cousins from both sides of the family are distinguished only by gender in terms of reference. Cross cousins are also lumped together and distinguished by gender.
