Summary of the genetic results. (A) PCA of modern West Eurasian populations with ancient data projected onto the two first PCs. Numbers under symbols represent the sample’s corresponding SNP (Single-Nucleotide Polymorphism) numbers in this analysis. (B) Genetic similarity probability maps for the period of death of the Octagon individual, based on 14C dates, and for three other preceding periods, where higher similarity probabilities are found45. (C) Genetic sexing results for the cranium and femur based on ratios of sequences aligning to the X and Y chromosomes46. Grey areas represent expected XY and XX distribution ranges, and crossed lines the standard error. (D) Relatedness estimation results using TKGWV2 (Top) and READv2 (Bottom). The top panel shows the simulated population coefficients after 1500 simulated relationships, based on 1644 overlapping SNPs between the cranium and the femur, that produced a Halved Relatedness Coefficient (HRC) of 0.409, above the simulated distribution for 1st degrees, and therefore suggesting an “Identical/Twins” relationship. The bottom panel shows the pairwise results for the three elements, as well as the result for the cranium-femur pair when restricting the genetic data to only transversions.
