Below is a plot for a K = 14 admixture analysis that includes eight new Scythian and Sarmatian genomes. The table above the plot gives some information for these samples.
The sample labeled Samara Scythian IA, which has appeared in previous plots, is I0247, from Samara, Russia. It is dated to 380–200 BC, and it belonged to the Caucasoid Y haplogroup R1a1a1b2a2a-Z2123 and the Mongoloid mitochondrial haplogroup G2a4.
The plot shows that the three Scythian and Sarmatian samples from the western part of the Eurasian Steppe had small amounts of the plain yellow Southern Mongoloid component and the light yellow Northern Mongoloid component, while the six Scythian samples from the eastern part of the Eurasian Steppe had much larger amounts of those components. The eastern Scythians of the Pazyryk culture generally had more Mongoloid admixture than those of the earlier Zevakino-Chilikta and Aldy-Bel cultures of the eastern region. The table below gives the Mongoloid admixture percentages for the nine samples.
