ABSTRACT The incidence of ABO and Rh (D) blood groups has been found to vary in various populations. The present investigation was undertaken with the aim to study ABO blood groups frequency among the Chokri of Chakhesang Naga, of Nagaland. The results were calculated as frequencies of each of the blood group, expressed as percentage. The frequency of blood group O (42.23%) was found to be the highest, followed by Blood group A (37.05%), B (16.73%) and AB (3.99%) was the least preponderant. The occurrence of Rh (D) was in very low frequency (0.4%)

Keywords: ABO and Rh (D) blood groups, Chokri, Chakhesang Naga, Nagaland.

INTRODUCTION MATERIAL AND METHODS In physical anthropology, more Blood sample of 251 individuals (126 particularly in populations genetics, the study of females and 125 Males) within the age group of different properties of blood was found in various 15-25 years were collected among the Chokri, population groups in the world plays an Chakhesang Naga from different villages of Phek interesting and important role. The distribution of district. An effort was made to collect the samples ABO blood group varies from one region to the from biologically unrelated individuals. For other, and also from one population to other. determining the ABO blood group, the Standard Thoughall the population of the world has same slide technique suggested by Lawler and Lawler blood group system, but the frequency of ABO and (1951) and Bhatia (1977) was followed. The Rh (D) antigens is found to vary amongst all method used for determining Rh factor is similar populations. with that of ABO blood grouping. For Rh blood Gosh (1969) calculated the average for grouping anti-D sera was used for typing the Rh , Pakistan, Sri Lanka, Nepal, Maldives factor. island and many anthropological studies have been carried out in India, which can be used for RESULTS AND DISCUSSION understanding the peopling of India .But in the The phenotypic distribution of ABO blood North-Eastern part of India it is relatively less groups and their allele frequencies for the total studied with very sparsely data report related sample of 251 Individuals are given in Table 1. to serological and biochemical traits on a few The percentage frequencies of O, A, B and AB population groups. To fill the gap, the present blood groups are 0.4223, 0.3705, 0.1673 and study focuses on the ABO and Rh (D) blood 0.0399 respectively. The blood group O showed groups distribution of the Chokri, Chakhesang the highest frequency followed by A, B and then Naga of Nagaland. AB blood group.
