Forty-eight Middle–Late Avar individuals provide a moderate-sized dataset for the Carpathian Basin (650–804 CE). The Y-chromosome distribution includes a notable count of haplogroup J (11 individuals), followed by R (4), N (3), single occurrences of GHIJK and C. Maternal diversity is pronounced: haplogroup H is most frequent (11), with eastern Eurasian-associated lineages G (5), M (5), F (3) and D (3) present.
Interpretation: the mixed maternal profile demonstrates significant input from both West Eurasian and East Eurasian maternal ancestries. Haplogroups M, D and certain sublineages of G and F are often associated with Inner Asian or Siberian origins in Eurasian prehistory, suggesting maternal gene flow from eastern sources into Avar communities. The presence of Y-DNA haplogroup N and C, and to a lesser degree J, further supports paternal links that include steppe and possibly Inner Asian ancestries; haplogroup R reflects wider European and Eurasian paternal lineages.
These patterns align with a model of multi-directional admixture: migrating groups with steppe and Inner Asian components mixed with local Carpathian Basin populations and with people connected to West Asian networks. The prominence of J among male lineages could indicate male-mediated gene flow from regions where J is common, but caution is needed: demographic processes (founder effects, social stratification of burials) can skew Y-chromosome frequencies. Because the sample size is 48, conclusions are moderate in confidence and should be refined with larger, geographically broader datasets and chronological resolution.
Genetic data therefore complements archaeological inference: an Avar population that was biologically diverse, mobile and connected across Eurasia.
