Extended Data Fig. 1: Population structure of wild barley.
From: A haplotype-based evolutionary history of barley domestication
(a) Individual ancestry coefficients in ADMIXTURE with the number of ancestral populations (K) ranging from 2 to 5. Individuals with ≥ 85% ancestry form were considered un-admixed samples. (b) Principal component analysis (PCA) based on 37.14 million biallelic SNPs with a MAF > 5%. The first three PCs are shown (PC1 vs. PC2 and PC1 vs. PC3). Un-admixed samples are colored to their major ancestry component in panel (a). (c) Distribution of pairwise identity-by-state (IBS) in the five wild barley populations. (d) Fixation indices (FST) in 1 Mb windows (shift: 200 kb) along the genome. All possible contrasts between any two of the five wild barley populations are shown.
