Below is a plot for a K = 13 admixture analysis that includes eight genomes from Mesolithic and Neolithic Latvia and Ukraine. The table above the plot gives some information for these samples.
The samples from the Mesolithic Kunda and Narva cultures are similar to the Mesolithic samples from Motala, Sweden, being made up mostly of the dark blue Western component, but also having about 25% of the medium blue Eastern component.
Latvia_HG3 and Latvia_MN1 are indistinguishable from the Western European hunter-gatherers in this analysis, being made up entirely of the dark blue component.
The hunter-gatherer sample from the Comb Ware culture is similar to the earlier hunter-gatherer samples from Karelia and Samara in Russia, being made up mostly of the medium blue Eastern component, but also having about 25% of the dark blue Western component.
The Corded Ware sample from Latvia is similar to the Pit Grave and Afanasevo samples, but with a bit less of the pine green Caucasus-related component. It has more of the medium blue component than any other sample in this analysis. It differs from all of the other Corded Ware samples in that it completely lacks the light blue early farmer component.
The Mesolithic sample from Ukraine and the sample from the Neolithic Dnieper-Donets culture of Ukraine are similar to each other, being made up mostly of the medium blue Eastern component, but also having around 35–45% of the dark blue Western component.
