Q2-L941 > YP4000 (Altai–Sayan microbranch)
Q-YP4000 is a small but important Altai Sayan branch within Q-L941. It appears among Turkic associated populations in the central and eastern Sayan region, including Tuvan and Altai groups, as well as among some Buryat and Evenk communities that have historically interacted with Turkic tribes. Although rare, Q-YP4000 is significant because it represents a Q2 lineage directly tied to the Altai Sayan population cluster that played a central role in the formation of early Turkic cultures.
Q-YP4000 is concentrated in the Altai and Sayan mountains. It has been detected in Tuvan and Altai individuals and at low frequency in Buryat and Evenk groups. The distribution highlights the contact zones between Mongolic, Tungusic and Turkic speaking peoples. Outside of this region the lineage is nearly absent.
On YFull, Q-YP4000 forms a shallow branch under Q-L941. The topology shows very little internal divergence, suggesting a relatively recent founder event followed by localised expansion in the Altai Sayan region.
Q-YP4000 is important in a Turkic focused atlas because it documents the presence of Q2 lineages within the Altai Sayan cluster, one of the core homelands of early Turkic and related groups. Its rarity increases its phylogenetic value as a population specific marker.
