The graphs A and B show the differences between
D’ (Figure 1A)
and Wn (Figure 1B) values
for the 10 two-locus haplotypes (HLA-A~HLA-C, HLA-C~HLA-B,
HLA-B~HLA-DRB1, HLA-DRB1~HLA-DQA1, HLA-DRB1~HLA-DPA1,
HLA-DRB1~HLA-DPB1, HLA-DQA1~HLA-DQB1,
HLA-DQB1~HLA-DPA1, HLA-DQB1~HLA-DPB1 and
HLA-DPA1~HLA-DPB1). The pre-fix “HLA-“
was omitted for the label of these haplotypes in the plots. The X-axis
represents the genomic distance of the two loci, the Y-axis shows
D’ (A) or Wn (B) values. Figures 1C-1F show heatmaps of LD measures [D’ (left
panel) and Wn (right panel)] for AFA, ASI, EUR and HIS. The
top-half (above the diagonal) represents the heatmap for the phased untruncated
allele name haplotypes, and the bottom half represents the heatmap for the
EM-estimated two-field allele name haplotypes.
