Regions of the OCA2 , DCT , KITLG and TYRP1 genes analyzed. (A) Mean amount of informativeness of a window centered on each SNP  for the three PERLEGEN populations. Black dots indicate SNPs present in PERLEGEN from the sequenced region. (B) Integrated haplotype score (iHS) statistic obtained from Happlotter  in the three HapMap populations for the region of interest. (C) Representation of the sequenced region.
