Ten directly dated Poltavka individuals provide a compact but informative genetic window. Seven of the ten male samples carry Y-chromosome lineages recorded broadly as R, indicating a strong prevalence of steppe-associated paternal ancestry. Mitochondrial lineages are diverse but dominated by haplogroup U (5 of 10), with additional H (2), U4b (1), I3a (1) and T (1) matrilines. Archaeological data combined with these DNA patterns paints a picture of male-biased continuity of steppe paternal lineages with a more mixed maternal pool.
On an autosomal level, published comparative frameworks show Poltavka individuals cluster with Middle Bronze Steppe ancestry — broadly similar to earlier Yamnaya-associated groups and showing affinities to later Sintashta/Andronovo-related populations. That genetic continuity helps explain archaeological continuities in pastoralism and mobility. However, caution is warranted: the sample set is small (10 individuals), geographically concentrated in Samara Oblast (Kutuluk III, Potapovka I, Zhuravlikha I, Grachevka, Bobrovka, Nikolaevka Kurgan and III, Lopatino II, Utyevka VI) and spans several centuries. Limited sample size and temporal spread mean fine-scale demographic processes (e.g., sex-biased migration episodes or subtle gene flow from neighboring forest-steppe groups) remain only partially resolved. Future sampling will refine patterns of continuity, admixture and social structure.
