Sex-biased admixture estimates among southern Africa Khoe-San and their descendent groups. A X chromosome to autosomal ratio for the Hessequa descendants based on the average ancestry proportion. Autosomal data is represented by the first 180 cM of chr 1–7, 10 and 12. Error bars represent two standard deviations based on 100 random sampling bootstraps. B Averaged ancestry proportion of supervised admixture for autosomes and X chromosome. Ancestries of mtDNA and Y chromosome haplogroups were assigned according to the haplogroup geographic prevalence. C X chromosome to autosomal ratio for the Khwe, Nama from Windhoek, ǂKhomani and Coloured population of Wellington
