Figure 2

Linkage disequilibrium structure of the ADM gene in the Chinese population HapMap sample. The black boxes in the ADM gene are exons. The solid lines show introns, and the dashed lines show the flanking regions. The numbers inside the squares are D′ × 100 (D′ values of 1.0 are not shown). The r² color scheme of Haploview was applied (r²=0 shown in white, 0<r²<1 shown in shades of gray, and r²=1 shown in black). The solid spine linkage disequilibrium method, as implemented in the Haploview software, was used to define the linkage disequilibrium blocks.
