The ancient DNA dataset from Eleke Sazy II is small (three individuals) but revealing when paired with archaeological context. Genetic typing shows one male individual carrying a Y‑chromosome haplogroup R, a lineage frequently observed among Eurasian steppe populations. Maternal lineages include mtDNA haplogroup J in two individuals and haplogroup A in one.
MtDNA J is often linked to West Eurasian maternal ancestry, while mtDNA A is associated with East Eurasian/Northeast Asian lineages. This combination — West‑leaning maternal J alongside an East‑linked A — suggests that the local maternal gene pool at Eleke Sazy contained mixed influences. The presence of Y‑R for the single male aligns with broader patterns where steppe paternal lineages played a major role in Iron Age pastoralist groups.
Crucially, with only three genomes sampled (<10), any broader demographic reconstruction is preliminary. Archaeogenetic studies across the Eurasian steppe show that Saka‑period groups commonly exhibit admixture between western steppe pastoralist ancestry and eastern Eurasian components; the Eleke Sazy results are compatible with this pattern, but more samples and genome‑wide analyses are needed to quantify admixture proportions, migration vectors, and kinship within and between kurgans.
Future targeted sampling (more individuals, additional sites) will clarify whether the mix of J and A mtDNA at Eleke Sazy reflects household‑level exogamy, long‑distance marriage networks, or shifting population dynamics across the Tarbagatai corridor.
