Figure 6. Pairwise linkage disequilibrium between deletion polymorphisms in the genome.

A. The majority of deletion polymorphisms are not associated strongly with each other. Pairwise LD was shown for CEU population. The number of pairs (y-axis) were plotted against −log₁₀(p-value) (top) and r² (bottom) (x-axis). B. Strong LD is uncommon between closely located deletion polymorphisms. For CEU (top), CHB+JPT (middle) and YRI (bottom), −log₁₀(p-value) (left) and r² (right) (y-axis) are plotted against the distance between each pair of deletion polymorphisms. For each plot, the figures for the GSTT2B-GSTT1 pair are indicated by a red circle.
