对7例东汉时期拓跋鲜卑遗存的线粒体DNA进行了遗传学分析。结合已发表的匈奴数据,在遗传多态性、单倍型组分布状态、Fst遗传距离、系统发育分析和多维度分析等方面,比较分析了拓跋鲜卑和匈奴的遗传关系。结果表明,拓跋鲜卑和匈奴之间有着较近的遗传关系,暗示拓跋鲜卑在其两次南迁过程中与匈奴发生基因交流的情况是存在的。
7 mitochondrial DNA (mtDNA) sequences from Tuoba Xianbei remains in Dong Han period were analyzed. Together with the Data of Xiongnu published, the genetic affinities between Tuoba Xianbei and Xiongnu were analyzed in genetic diversity, haplogroup status, Fst genetic distances, phylogenetic analysis and multidimentional scaling (MDS) analysis. The results indicated that the Tuoba Xianbei presented the closer affinities to the Xiongnu, which implied that there was the gene flow between Tuoba Xianbei and Xiongnu during the 2 southward migrations.
