Plasmodium falciparum parasites exist as genetically distinct haploid clones in infected people. In the Kilombero valley in south-east Tanzania, at least 85% of the inhabitants of Michenga village harbour more than one clone. Using 2 highly polymorphic unlinked markers, it has been estimated that each infected person harbours between one and 6 P. falciparum clones at any one time, with a mean of 3.5 clones. When mosquitoes acquire gametocytes of 2 different clones in a blood meal, crossing generates recombinant clones differing from their parental genotypes. The inbreeding coefficient of the parasite population has been estimated as 0.33.
