Figure 10.

Peak regions harbouring areas at or approaching fixation. (a-c) Boxplots by population: (a) RCL0 SNP counts; (b) RCL0 length (kb); (c) RCL0 extent value (cM). (d) One each of the top autosomal and top chromosome X candidate fixation peak regions from Table S7a-c in Additional file 2 for each population, and the centimorgan values from PEmat for the chromosomal area ± 1 peak region width from the center plotted as a grayscale image. Grayscale levels are adjusted relative to the maximum value in the 90th percentile and values above that level set to black; legend key between gray levels and cM is indicated at the top of each panel. Red line: smoothed extAUC values were down-sampled at a 10% frequency and plotted. The left-hand y-axis labels refer to percentile levels of the PEmat data, and the right-hand y-axis labels are for the line plot of extAUC values. Outlier points in (a-c) are randomly jittered to reduce overlap and datapoints off the figure plotted as diamonds.
