Figure 1From: Genome-wide SNP genotyping highlights the role of natural selection in Plasmodium falciparumpopulation divergenceDiversity at assayed SNPs (SNP π). (a) Nonsynonymous and silent SNP diversity by population. Significantly lower nonsynonymous SNP diversity (determined by bootstrapping) is indicated by asterisks: *P < 0.05; **P < 0.001; ***P < 0.0001. Error bars indicate 95% confidence intervals derived from bootstrapping. (b) SNP π on chromosome 7 for chloroquine resistant (red) and chloroquine sensitive (blue) samples. The disparity in diversity near 460 kb indicated with gray shading likely corresponds to a selective sweep associated with the pfcrt locus.Back to article page
