Figure 5.

Linkage disequilibrium (LD) measure r² plotted vs. the physical map distance (Mb) between pairs of SNPs in the association panel located on (A) chromosomal short arm, (B) chromosomal long arm, (C) both arms combined (euchromatin), and (D) whole chromosome region. The illustrations include combined analyses for all 12 chromosomes except chromosomal short arm for which chromosome 2 is excluded as it is pericentric. The trend line of the nonlinear quantile regression of r² (90^th percentile) vs. the physical map distance between the SNP markers is depicted in red, dashed blue line depicts the standard LD decay threshold (r² = 0.1).
