Native Americans and the law, c2000:p. 43 (The term "blood quantum" is used to refer to the fraction of Indian blood present in an individual applying for membership in a federally recognized Indian tribe. To count toward membership in a federally recognized Indian tribe, Indian blood must be that of a recognized tribe. A person can have blood from more than one Indian tribe, but most tribal constitutions and existing federal law allows a person to claim membership in only one Indian tribe. The quantum of Indian blood (from none to entirely Indian blood) necessary to be considered for membership varies from tribe to tribe)
