A The admixture models of Mongolia_LBA_DSKC and Altai_MLBA individuals. The colors indicate different ancestry sources used to model Mongolia_LBA_DSKC and Altai_MLBA. The length of the boxes indicates the genetic contribution of the ancestry, and the horizontal bars indicate the one standard errors. B The heatmap of the average length of IBD blocks shared among LBA/EIA individuals. We grouped individuals into four groups, based on their mortuary affiliation and genetic profiles: Altai_MLBA, DSKC (including 23 individuals from Mongolia_LBA_DSKC and 2 culturally DSKC affiliated individuals with ANA-like genetic profiles), figure-shaped, and Slab Grave. Individuals associated with similar cultures shared more IBD, leading to the clustering of the populations with the similar mortuary affiliation. C The violin plot comparing the total length of IBD shared (1) between Altai_MLBA (n = 8) and Mongolia_LBA_DSKC (n = 25) and (2) between Altai_MLBA and figure-shaped individuals (n = 11). The sum IBD length of each pair is shown as the colored symbols. The two-sided p-value for the Wilcoxon rank-sum test is shown at the top of the plot. Source data are available in Supplementary Data 7, 8, 15, and 17.
