A study of ABO and Rh D polymorphisms was conducted on 923 Tibetans living in exile in four different places (both high and low altitudes) in India. The frequencies of alleles p, q, and r for the ABO blood group system were found to be 0.1295, 0.2544, and 0.6152, respectively, and for alleles D and d of the Rh blood group system the allele frequencies were 0.9428 and 0.0572, respectively, for the total data. No significant difference was found for the allele frequencies among the four places for the two blood group systems. The allele frequencies were in Hardy-Weinberg equilibrium for the ABO blood group system and show East Asian affinity for the Tibetans. KEYWORDS: ABO, RH, TIBETANS, INDIA., Tibetans have been living in different parts of India for the last 45 years. We studied the ABO and Rh D blood group polymorphisms among Tibetans at four settlements (at [...]
