Hypodescent is the practice of determining the lineage of a child of mixed race ancestry by assigning the child the race of his or her more socially subordinate parent. Because recent history shows Caucasians being socially dominant in the Western world, mixed race children are most commonly assigned to their non-Caucasian parent.
In societies that regard some races or ethnic groups of people as dominant or superior and others as subordinate or inferior, hypodescent refers to the automatic assignment by the dominant culture of children of a mixed union or sexual relations between members of different socioeconomic groups or ethnic groups to the subordinate group.[1] The opposite practice is hyperdescent, in which children are assigned to the race that is considered dominant or superior.
