Properdin factor B (Bf) distribution in North and Central American populations

A study of properdin factor B (Bf) in 22 North and Central American populations demonstrated gene clusters delineating Old World Caucasian, New World and Black Ancestoral groups. Result of gene frequencies were comparable to data in the literature of European Caucasian and African Blacks. New World indigeneous population were clearly separated from other racial groups with hybrid population clustering in between the major genetic contributions.
