Pairwise LD between the candidate marker SNP8 and other seven flanking markers in unrelated African-American subjects. [D' = 1.00 in the blank squares; the numbers inside the red squares are D' × 100%; the blue squares represent low r² values; the white squares represent low D' and low r² values. SNPs 1–7 were reported previously in Luo et al. (2006) and span from 3' to 5'.].
