Fig. 1From: Confounding of linkage disequilibrium patterns in large scale DNA based gene-gene interaction studiesTwo LD block structures on two chromosomes: Presented are two LD blocks corresponding to HapMap3 GBR subpopulation of 91 unrelated individuals. The selected regions are from chromosome 8 (left) and 7 (right) consist of 787 and 964 SNPs respectively. The positions of causal epistatic variants are indicated by arrowsBack to article page
