Histograms of the pairwise divergence among selected haplotypes. The coordinate system is the same as that employed in Figure 1. Divergences were calculated for 1-kbp bins, based on RefSeq coordinates, counting only discrepancies at nucleotide positions that could be fully aligned with all other haplotypes for which sequence was available in a given region. (A) Representative C-group haplotype compared to a representative E-group haplotype. (B) Recombinant haplotype 04535_1 compared to a representative C-group haplotype. (C) Recombinant haplotype 04535_1 compared to a representative E-group haplotype. (D) A representative B-group haplotype compared to a representative D-group haplotype. The actual haplotypes used to represent haplotype groups B, C, D, and E (see legend to Fig. 1) were 01018_2, 00576_1, 00576_2, and 10923_2, respectively.
