dc.description.abstract The antigen and phenotype frequencies of ABO and Rhesus blood groups were determined in Guraan ethnic group. Blood group O was found to be the most frequent (37%). The frequency of blood group A was 36%, for group B 22% and for group AB 5%. In Rhesus blood grouping system the frequency of Rh (D) positive was 93%. With respect to both ABO and Rh (D) positive prevalence of group A along with Rh (D) positive was 34%, group O+ve was 34% , B+ve 20% and AB+ve was 5%.The frequencies of other Rh antigens were e 99%, c 94%, C 37% and E 12%. The Rh phenotype frequency was ccDee 47%, CcDee 32%, ccee 7%, ccDEe 6%, CcDEe 5%, CCDee 2% and ccDEE 1%.The trend can be shown with a general formula O>A>B>AB. Group A (37.9%, 35.2% respectively), B (31%, 18.3% respectively) and AB (6.9%, 4.2% respectively) were more frequent in females as compared to males. In contrast blood group O was more prevalent in males (42.3%) as compared to females (24.1%). There was a real predominance of blood group O over the blood groups A, B and AB as well as Rh (D) positive over Rh (D) negative. Predominance of blood group A in females was also reported. e antigen (100%, 96.6% respectively) and C antigen (40.8%, 27.6% respectively) were more frequent in males than in females while, in contrast, c antigen (96.6%, 93% respectively) and E antigen (17.2%, 9.9% respectively) were more frequent in females than in males. The Rh phenotype CCDee (28%) in males, but absent (0%) in females. In contrast the Rh phenotype ccDEE (3.4%) in females, but absent (0%) in males. en_US
