title: Genetic analyses of Xianbei populations about 1,500-1,800 years old.
abstract: To understand the profile of genetic structure of Xianbei and trace its impacts on the formation and development of the minorities from northern China, we analyzed the sequences of the hypervariable segment I (HVS-I, 16.035-16.398) in mtDNA control region of 17 Tuoba Xianbei remains from Shangdu Dongdajing cemetery (Inner Mongolia). Its haplotype diversity and nucleotide diversity were 0.971 ± 0.032 and 0.0184 ± 0.010, respectively, and the haplogroup status presented 29.5% C, 23.5% D4, 17.6% D5, 17.6% A, 5.9% B and 5.9% G. When the data from Qilang Mountain Tuoba remains and other relevant populations were considered, we found that Dongdajing Tuoba Xianbei presented the closest genetic affinity to Qilang Mountain Tuoba Xianbei. Tuoba Xianbei and Murong Xianbei showed a significant differentiation in the maternal lineages. Tuoba Xianbei may contribute to the gene pool of some northern minorities, and it may mix with Xiongnu in northern China.
