Figure 4

Measures of contiguous homozygosity surrounding outlier peak regions. Two of the top four peak regions were chosen from Table 3 for each population and centimorgan values from the percentile extent matrix (PE_mat) for the surrounding 10-Mb chromosomal area plotted as a grayscale image. Grayscale levels are adjusted relative to the maximum centimorgan value in the 90th percentile and values above that level set to black; correspondence between gray levels and cM is indicated at the top of each panel. Red line: smoothed ext_AUC values were down-sampled before plotting. The left-hand y-axis labels refer to percentile levels of the PE_mat data, and the right-hand y-axis labels are for the line plot of ext_AUC values.
