A total of nearly 1,000 persons belonging to a number of caste, religious and tribal groupings in Kerala and the Nilgiri Hills of South India have been tested for genetic variation in 4 blood group, 5 serum protein and 17 enzyme systems as well as haemoglobin. The distribution of blood groups, serum protein and enzyme groups is similar to that reported for other South Indian populations. Abnormal haemoglobins were detected in several populations. Abnormal haemoglobins were detected in several populations, HbS being present in more than 20% of the Irula and Kurumba in the Nilgiri Hills. In the Kerala populations there were 4 examples of Hb AD and 1 of Hb AE. Genetic distance estimates using the gene frequency data indicate that the closest groups are the Nayar and Izhava and the Brahmin and Nayar. The tribal populations are approximately twice as far from the Nayar as they are from the Izhava. The Todas of the Nilgiri Hills are somewhat closer to the Brahmin of Kerala than they are to the other tribal populations.
对印度南部喀拉拉邦和尼尔吉里丘陵地区多个种姓、宗教和部落群体的近1000人进行了检测，分析他们在4种血型系统、5种血清蛋白系统、17种酶系统以及血红蛋白方面的基因变异情况。血型、血清蛋白和酶类的分布情况与其他南印度人群的报告相似。在多个群体中检测到了异常血红蛋白。在尼尔吉里丘陵地区，超过20%的伊鲁拉人和库伦巴人携带血红蛋白S（HbS）。在喀拉拉邦人群中，发现了4例血红蛋白AD（Hb AD）和1例血红蛋白AE（Hb AE）。利用基因频率数据估算的遗传距离表明，关系最密切的群体是纳亚尔人和伊扎瓦人，以及婆罗门人和纳亚尔人。部落群体与纳亚尔人的距离大约是与伊扎瓦人距离的两倍。尼尔吉里丘陵地区的托达人与喀拉拉邦的婆罗门人相比，与其他部落群体的关系更近一些。
