Linkage disequilibrium in PvDBP II. . Patterns of pairwise linkage disequilibrium (r2) in the PvDBPII-encoding gene from Brazilian isolates. (A) Linkage disequilibrium was calculated for SNPs for which the frequency of the minor allele was at least 0.1 in the entire sample. White: r2= 0; black: r2= 1; shades of gray: 0 <r2< 1. The bracket indicates the cluster of amino acids with the highest r2. (B) LD was calculated as previously described but not including the Amapá population.
