Pyrograms generated from a PSQ 96MA showing peak profiles for dhfr at codon 59 (A) and dhps at codon 613 (B), given here to illustrate how the results were reported. SNP sites are marked by open areas on the pyrogram. (A) T/T, wild type; C/C, mutant allele; T/C, mixed alleles. (B) Three allelic types at the same position could also be reported. The percentages of SNPs were used for double checking the scores of alleles, in addition to the SNP calling pattern.
