Crow kinship

The relatives of the subject's father's matrilineage are distinguished only by their sex, regardless of their age or generation.

In contrast, within Ego's own matrilineage, differences of generation are noted.

The system is associated with groups that have a strong tradition of matrilineal descent.

As with the Iroquois system, the Crow uses bifurcate merging, meaning that there is a distinction between collateral relatives of different gender in Ego's descent group.

In the Southwestern US, it has traditionally been part of the Hopi Indian culture and the Navajo Nation.
