Geographical representation of the admixture coefficients through spatial kriging with low (cool colours) to high (hot colours) representing mean (TESS) admixture proportions. Individuals are classed from the non-admixture analysis in TESS with different colour and/or shapes representing different clusters. The green represents the Bantu and the pink represents the Khoisan. Map created using R 3.0.372 (http://www.R-project.org) package spatial 7.3.97173 and maps 2.3.97274.
