俫人ABO血型的调查与研究

A SURVEY OF ABO BLOOD GROUPS OF THE LAI PEOPLE IN GUANGXI

本文报告用玻片快速检验法对分布于桂西滇黔桂接壤地区的待识别民族俫人ABO血型的调查结果。俫人ABO血型的基因频率是:p=0.1189,q=0.3201,r=0.5610。俫人的血型分布特点是B>O>A,在我国南方诸民族中,俫人与海南省黎族的ABO血型分布特点相同。与周围民族的聚类分析的结果表明俫人与黎族具有最近的遗传距离,因而在系统树中聚类为一组。俫人与黎族可能共同起源于古越族的支族俚人。

An anthropological research on 122 Lai people living in the Yunnan-Guizhou Plateau was carried out in 1988. The Lai people has attributed no definite ethnic group yet. Their ABO blood groups were determined. The A, B, O and AB phenatype frequencies of ABO blood groups in Lai people are 0.1721, 0.4836, 0.2951 and 0.0492. The p, q and r gene frequencies of ABO blood groups in Lai people are 0.1189, 0.3201 and 0.5610. The \D/a\ test according to Hardy-Weiberg's law is good. The frequency of ABO blood groups in Lai people is obviously higher than that in the Han series, except the Northern Han series, and is very near to the Li people in Hainan Island and Tai in Tailand. It is implied in this connexion that the Lai people has a close genetic relation with the Li people. Much work done by other authors on the ethnological aspects, cultural anthropology and archaeology has led to the conclusion that Lai tribe has a close racial relation with Li group and both groups may originate from a same ancester living in Southern China. This conclusion is confirmed by the results of our research.
