Observed haplotypes of SNPs related to resistance to CQ, SP and artemisinin derivatives. A haplotype is defined by the combination of mutations in genes related to drug resistance. Grey indicates mutations and white indicates wild-type. Two different haplotypes were observed in genes pfmdr1 and pfcrt. One haplotype was observed in genes pfdhfr and pfdhps. One haplotype was observed in gene pfATPase6. n corresponds to the number of samples assessed for the analysis.
