Figure 4From: Population diversity and antibody selective pressure to Plasmodium falciparum MSP1 block2 locus in an African malaria-endemic settingFrequency distribution of the number of tri-peptide motif usage in the DK and DM alleles. A: Frequency distribution of K1-type alleles (DK alleles) by number of distinct tripeptides present. B. Frequency distribution of Mad20-types (DM alleles) by number of distinct tripeptide nucleotide sequences present (DMR, DMRK and MK hybrids excluded). C. Frequency distribution of Mad20-types DM alleles (by number of distinct tripeptide protein sequences present (DMR, DMRK and MK hybrids excluded).Back to article page
