It also appears to be quite similar for the tribes of North America, except for the exception that about 80% of the Blackfoot Indians of Montana have blood type A. Repeatedly the claim has been brough up that Cherokees might have had a high percentage of rh negative blood. Here is a study from 1962 putting this claim to rest: The Rh types are set forth in table 5. As all blood samples were positive with anti-Rho (D), gene frequencies could be obtained by counting. The most common phenotypes are Rh1Rhl (DCe/DCe) and Rh1Rh2 (DCe/DcE), and … Continue reading Are Cherokees high in rh negative blood?
