Comparison of the extent and frequency of homozygous segments with founder haplotypes underlying extAUC peaks. Minimum segment length (Extentmin), expected haplotype frequency (Freqhap-exp), and maximum haplotype frequency (Freqhap-max) were calculated as diagrammed in Figure 5 for peaks dichotomized into non-outlier and outlier peaks. Data points were colored using a two-dimensional density estimate using R's function densCols with nbin = 1,024. Data shown are for CEU with plots for all populations in Additional file 9.
