Figure 3.

Decay of linkage disequilibrium (LD) over distance. LD was measured by pairwise comparison (A&C, r2 ≥ 0.5; B&D, r2 ≥ 0.8) between markers that had minor allele frequency ≥ 0.05 (A, B), ≥ 0.1 (C, D) and that fell into the same intermarker distance bin. Blue lines denote Mlabri, black lines denote YRI, others include the rest 15 population samples.
