X-linked Blood Groups, Xg, in Australian Aborigines and New Guineans

Article metrics


SINCE the discovery of the X-linked blood groups Xg by Mann et al.1, the results of many important genetic studies on these unique blood groups have been reported. Race and Sanger2 tabulated the Xga frequencies for different racial groups and noted that Chinese and Negroes have a lower Xga frequency than other peoples tested, and that Navajo Indians have the highest frequency, just slightly higher than that for Sardinians. In each study reported, the blood samples had been collected from unrelated individuals.
