Pairwise linkage disequilibrium between <i>KIR</i> genes in the family sample.

<p>This analysis was based on the genotypes reconstructed after the first step, without using any information about LD pattern between <i>KIR</i> genes. Each square represents the magnitude of pairwise LD between <i>KIR</i> genes, as measured by D' (panel A) or r² (panel B). Red squares represent a |D'| or r² value of 1.0, corresponding to complete and perfect LD, respectively. Orange, yellow, and white squares indicate |D'| or R² values of [0.75-1[, [0.5-0.75[, and<0.5, respectively.
