Fig. 7: Unsupervised admixture analyses of European ancient individuals with three clustering populations, where Anatolian farmers, Steppe individuals and Western Hunter-Gatherers (WHG) are split into the three clusters.

a Resulting admixture proportions and clusters for the reference and the 21 European individuals in this study, with validation results on top and imputed 1x below. b Admixture estimates for each of the three clusters obtained with imputed 1x (triangles) and validation (full circles) data for each of the 21 individuals, where error bars represent one standard error of the estimates. c boxplots (where horizontal lines represent, from bottom to top, the first quartile, the median and the third quartile, and the whiskers lengths are 1.5 times the interquartile range) of the differences between the values of ancestry components obtained with the high-coverage and imputed data across all depths of coverage (n = 21 independent European individual samples).
