Fig. 3

SNP presence distributes the methylation data into three tiers. All examples illustrated using 95 southern Africa samples. a DNA methylation beta-values at a single SNP site plotted across all samples. b Data from 40 randomly selected sites with SNP-like three-tier patterns plotted together across all samples to illustrate the need for variability in cutoff values used at each SNP position. c The same data as in (b) is shown separately for each array probe (i.e., genome locus). Probe-wise thresholds allow separation of data into three tiers
