Sulfadoxine–pyrimethamine selective sweep characteristics at three sites with different prevalence of malaria parasites. Expected heterozygosity in microsatellite loci flanking DHFR 51I/59R/108N (a) and DHPS 437G/540E (b). Samples with missing data were excluded. Error bars represent ±1 standard deviation. Dashed lines represent genomic level, average He, based on unlinked loci. Alpha <0.05 asterisk indicates significant difference between two study sites based on permutation
