Fig. 6: Population-level chromosome painting of all marker effects for bio1—the color in each cell (marker-individual combination) represents the marker effect for that individual for mean annual temperature.

The x-axis represents marker positions for each marker from a 9K Illumina Infinium iSelect Custom Genotyping BeadChip, this means that marker spacing is uneven across each chromosome, thus positions are in slightly different places on each chromosome. The y-axis represents each individual line in each subpopulation, for East African (Population 1, n = 89), Levant/Mediterranean (Population 2, n = 205), North African/Mediterranean (Population 3, n = 117), Northern Europe (Population 4, n = 95), and Asia (Population 5, n = 278).
