Ancestry profiles produced by Structure showing population structure inference of 66 316 SNPs from 93 whole genomes of S. cerevisiae. Each bar represents an individual strain and colours represent different inferred populations for K = 4 (optimal). The geographic origin and niche of isolation for each strain is labelled with coloured squares and circles, respectively. Approximately the orange inferred subpopulation correlates with the European/wine group, the purple with Sake and the blue possibly Asia/Africa; there are not clear correlations with the yellow inferred subpopulation.
