Alleles of the MSP-2 gene showing unevenly distributed FC27 and 3D7 alleles among children of the same household. a A household where the children were infected with only one allele type (either FC27 or 3D7). b A household where child 1 had an infection with only FC27 allele type while child 2 had an infection with only 3D7 allele type, but child 3 had mixed infection of both FC27 and 3D7 allele types. In addition, child 1 and 3, as well as child 2 and 3 had an infection with parasites of the same genotypes with respect to their allele types and well as fragment sizes. The numeric codes represent the children in the respective household
