中文摘要：分析48个锡伯人线粒体DNA高可变Ⅰ区的遗传多态性,并与已发表的相关人群线粒体DNA数据进行比较.结果表明,在48个序列中共检测出43个突变位点,界定了35种单倍型,其线粒体DNA1序列多态性为0.982,核苷酸多态性为0.018,而其平均核苷酸差异为5.922.人群比较分析表明,锡伯人与古代拓跋鲜卑人有最近的亲缘关系,同时也表现出与中国北方游牧民族有较近的亲缘关系,推断锡伯人可能是拓跋鲜卑的后裔.

英文摘要：48 sequences of hypervariable segment Ⅰ(HVS-Ⅰ) in mitochondrial DNA control region from Xinjiang Xibe population were analyzed,in which,35 haplotypes were found by 43 polymorphic sites.The haplotype diversity and nucleotide diversity are 0.982 and 0.018,respectively,and the mean of nucleotide number differences is 5.922.When the data from relevant populations published were considered,it was found that the Xibe ethnic population presented the closest genetic affinity to ancient Tuoba Xianbei population and,also showed a closer genetic affinity to the nomadic populations from northern China,suggesting that the Xibe people may be the descendants of the ancient Tuoba Xianbei.
