The Ajv70 like Ire8 individual belonged to a 2800-2000 BC Pitted Ware Culture complex found in Ajvide, Gotland, Sweden. Ajv70 belonged as Ire8 to mtDNA hg U4. The PWC was a hunter gatherer culture.
The Ajv70 genome had in common 421k SNPs vs the 1000 genome reference individuals. These was as with the earlier analysis for Ire8, Gok4, Ste7 and La Brañas (se earlier posts) imputed using BEAGLE with the same reference panel as before using both project individuals and public reference populations. The populations was further LD pruned in PLINK down to 105k SNPs and run through Chromopainter-Finestructure unlinked pipeline. The European panel was extracted from a world Chromopainter run output files resulting in about 85k SNP's for Finestructure analysis. The high number of SNPs should give good resolution for further analysis.
The result for Ajv70 above heatmap appears not to give a clear clustering to any modern European populations as Ajv70 doesnt fit into any heatbox clusters and branch out very early from the rest of the European tree, in other words no more systematic affiliation as we have seen in the analysis of the Ire8, Gok4, Ste7 and the La Brañas. There is however no doubt that Ajv70 belongs to the more northern populations in Europe if looking at the PCA plots below..
Ajv70 appears not to fit very well any specific modern European population but appears for certain northern, but at group level (infered from 289k analysis) from the heatmap colours Ajv70 appears to be somewhere between SA4, SWE-SAM, AUS1, NO6 and EST.
This analysis also oppose the following claim about Ajv70 made by other genome bloggers:
"Prehistoric Scandinavians genetically most similar to modern Poles"
