Distribution of iHS values per SNP on a the nearby chromosomal regions for a set of 15 genes (shown here as example) in the Asparagine N-Glycosylation pathway that show a signature of positive selection in at least one continental group. The same representation but for all the genes in the pathway is presented as Supplementary Figure S3. Points in darker gray represent SNPs inside the gene. A blue smoothing line (calculated with the Loess function) is shown to facilitate the reading. Note that although 800 kb regions are plotted here, only the SNPs within 100 kb upstream and downstream of the gene have been included in the analysis.
