A note on the frequency distribution of AB0 and Rhesus blood groups in four Thai populations of Assam (India) and their position among the Mongoloids of this region

An attempt has been made to give a picture of the distribution of AB0 and Rhesus blood groups in four Thai populations of Assam, India. Intragroup heterogeneity and their position among the Mongoloid populations of this region have also been examined. In all of these groups the frequency of the 0-allele was found to be the most predominant one followed by B- and A-alleles, respectively. A similar trend is observed in some other populations of Asia. The populations under study show statistically similarity with none of the Mongoloid populations of Assam. The incidence of Rhesus-negatives in the populations under study ranges from complete absence to below 2%.
