Frequency distributions of MAD20-like allele frequencies of msp1 block 2. a Overall, 123 different allele sequences were detected among 621 MAD20-like msp1 block 2 sequences determined by assembly of short sequence reads, of which 62 of these occurred only once. The proportion of each as a percentage of all 621 MAD20-like sequences is shown. b Nine MAD20-like msp1 block 2 sequences accounted for more than 5% in either Africa or Asia. The proportion of these MAD20-like alleles in Africa (185 MAD20-like sequences) and Asia (436 MAD20-like sequences), and the translated amino acid sequences of these alleles are shown. Amino acid sequences of all alleles detected are shown in Additional file 9
