With a view to trace the Mongol expansion in Tuvinian gene pool we studied two largest Tuvinian clans – those in which, according to data of humanities, one could expect the highest Central Asian ancestry, connected with the Mongol expansion. Thus, the results of Central Asian ancestry in these two clans component may be used as upper limit of the Mongol influence upon the Tuvinian gene pool in a whole. According to the data of 59 Y-chromosomal SNP markers, the haplogroup spectra in these Tuvinian tribal groups (Mongush, N = 64, and Oorzhak, N = 27) were similar. On average, two-thirds of their gene pools (63 %) are composed by North Eurasian haplogroups (N*, N1a2, N3a, Q) connected with autochtonous populations of modern area of Tuvans. The Central Asian haplogroups (C2, O2) composed less then fifth part (17 %) of gene pools of the clans studied. The opposite ratio was revealed in Mongols: there were 10 % North Eurasian haplogroups and 75 % Central Asian haplogroups in their gene pool. All the results derived – “genetic portraits”, the matrix of genetic distances, the dendrogram and the multidimensional scaling plot, which mirror the genetic connections between Tuvinian clans and populations of South Siberia and East Asia, demonstrated the prominent similarity of the Tuvinian gene pools with populations from and Khakassia and Altai.  It could be therefore assumed that Tuvinian clans Mongush and Oorzhak originated from autochtonous people (supposedly, from the local Samoyed and Kets substrata). The minor component of Central Asian haplogroups in the gene pool of these clans allowed to suppose that Mongol expansion did not have a significant influence upon the Tuvinan gene pool at a whole.

俄罗斯联邦图瓦加盟共和国在阿尔泰加盟共和国东边、布里亚特加盟共和国西边。其总人口的近一半来自境内26个部族中的7个被民族志学家认为受过蒙古民族较大影响的部族。其总人口的33%来自这7个部族之中的两个:Mongush,Oorzhak。

测了下列59个SNP:M130, M217, F2613, F2386, F1788, F3918, F3830, M86, F5485, SK1066, F3791, F11899, F5481, F11791, F14768, F3960, P53.1, CTS4021, M407, Z12266, M174, M69, M170, M253, M223, P37, M304, M267, M172, M47, M67, M92, M12, M9, M20, M231, LLY22g, M178, L708, L666, B211, M2118, VL29, Z236, F4205, P31, M122, M242, M120, M378, M207, M198, M458, M343, M73, M269, M124, M70, and chrY:15310670 T>C.

测量结果的Mongush 64人样本Y单倍群中N和Q占58%、C和O占20%,Oorzhak 27人样本Y单倍群中N和Q占67%、C和O占15%。结论是影响不算太大。

附上2013年一篇文章发表的测量结果:

R1a1a在这些族系中的频度还是蛮高的,估计与匈奴大墓的R1a1a1b存在前后继承关系~
