Overall linkage disequilibrium.

Wn is displayed for each gene pair in a full-length KIR haplotype. Lighter shades indicate lower linkage disequilibrium and represent Wn approaching 0. Darker shades indicate higher linkage disequilibrium and represent Wn values approaching 1. Since they are now considered to be a single locus, KIR2DL2 and KIR2DL3 were combined into KIR2DL2L3; similarly, KIR2DS3 and KIR2DS5 were combined into KIR2DS3S5.
