Genetic data from 92 individuals spanning 1499 BCE to 884 CE provides a clearer picture of ancestry and mobility across the steppe. Y-chromosome markers are diverse: R is most common (26 instances), accompanied by Q (10), J (10) and a small number of E (2). Mitochondrial diversity likewise spans west and east Eurasian lineages: U (20), T (7), D (6), H (5) and C (5). This mix indicates repeated admixture between western steppe-associated males (R lineages often associated with broader Indo-European steppe ancestry) and eastern/Inner Asian maternal contributions (D, C), consistent with archaeological evidence for interaction zones.
The genetic pattern suggests a core West Eurasian steppe ancestry blended over time with eastern or Siberian components, particularly in Xinjiang sites (Bolati, Axile, Wutulan, Qiafuqihaishuiku) where eastern mtDNAs are more frequent. Haplogroup J and E occurrences point to gene flow from more southerly or Near Eastern sources, perhaps via trade networks or incorporation of diverse groups. While 92 samples give substantial resolution, geographic sampling is uneven—many specimens come from Xinjiang and Chilpek mounds—so regional conclusions should be treated cautiously. Where sample counts are low (<10) for particular sites or subperiods, interpretations remain preliminary and require more data.
