摘要：All human populations share the same known blood systems. The best-known blood type classification is the ABO system, which is often coupled with another system, the Rhesus blood type (expressed as Rh+ve or Rh-ve). Overall, in human, the O blood type (usually resulting from the absence of both A and B alleles) is very common around the world while the majority of the human in the world have the Rh+ve blood type. The goal of the present study was to find out the distribution and prevalence of ABO and Rh Phenotype blood groups in the students’ population belonging to different tribes. A total of 664 blood samples were collected over a period of one year from the students of BSc and BCom belonging to 21 different tribes of the state. However, due to insignificant number of some tribes, only students from five tribes were considered for the data interpretation namely Nyishi(378)>Galo(81)>Apatani(51)>Tagin(51)>Monpa(41). Accordingly, determination of various blood groups namely (ABO and Rh) blood groups were performed. Results: Out of the total sample the most common blood was O blood group comprising 263 (39.6%) followed by A group 181 (27.3%), B 161 (24.24%) and AB 59 (8.9%). 656 (98.8%) of the total samples were Rh positive while 8 (1.2%) were Rh negative. The distribution of blood group O was highest among the students closely followed by A, B and AB. The frequencies of Rh positive and Rh-negative students are 98.8% and 1.2% respectively.
