Abstract

Four polymorphic sites of the short arm of the X chromosome were studied in two racial groups from India, the Assamese and the Malayalee. Since the allelic frequencies of the two groups did not differ markedly from each other, the data from the two populations were pooled. The frequency of the A2 allele was 0.57 for the L1.28 probe, 0.20 for the RC8 probe, 0.28 for the pD2 probe and 0.11 for the L754 probe. The A3 allelic fragment of the RC8 probe was not found among 67 Indians, and in one Assamese woman an additional 7.0-kilobase fragment was found. The differences between the Indian population and other ethnic groups were analyzed.

摘要

在来自印度的两个种族群体阿萨姆人（Assamese）和马拉雅拉姆人（Malayalee）中，对X染色体短臂的四个多态性位点进行了研究。由于这两个群体的等位基因频率彼此差异不显著，因此将两个群体的数据合并。对于L1.28探针，A2等位基因的频率为0.57；对于RC8探针，为0.20；对于pD2探针，为0.28；对于L754探针，为0.11。在67名印度人中未发现RC8探针的A3等位基因片段，并且在一名阿萨姆女性中发现了一个额外的7.0千碱基片段。分析了印度人群与其他种族群体之间的差异。
