Additional Figure 1 - Ancestry assignment for Qatari individuals for entire genome. Ancestry assignments for Qatari individuals. (top) Locus-specific ancestry assignment from SupportMix colored by most probable ancestral population as in Figure 4 (shades of blue for Middle Eastern populations, reds for Asian populations and shades of green for African populations). Each individual haploid genome is represented by one column ordered top to bottom from the beginning of chromosome 1 to the end of chromosome 22. (bottom) Corresponding global ancestry assignment by STRUCTURE. Each individual (vertical bar) is colored by the proportion to the estimated ancestry in the k = 3 clusters.
