Scan for evidence of population specific directional selection using the Rsb cross-population test for extended haplotypes. Positive values indicate SNPs associated with longer haplotypes in the Kintampo population sample, whereas negative values indicate SNPs associated with longer haplotypes in the Navrongo population sample. One region contains at least 2 SNPs with Rsb values above 5 indicating a potentially stronger signature of selection in Kintampo on chromosome 14 while 3 regions contain at least 2 SNPs with Rsb values below −5 indicating a potentially stronger signature of selection in Navrongo on chromosomes 10, 12 and 13 (marked with asterisks). The regions, and genes within them, are detailed in Fig. 8 and Additional file 1: Table S4. Three of these four regions were associated with high |iHS| windows in both populations (Figs. 5 and 6, Additional file 1: Table S3)
