Fig. 3From: Global diversity of the gene encoding the Pfs25 protein—a Plasmodium falciparum transmission-blocking vaccine candidateHaplotype network of Pfs25 gene of Plasmodium falciparum. Each circle indicates a unique haplotype, and the sizes of the circles are proportional to the haplotype frequencies of each network. Each cross line represents one mutation step. Colors inside the circles indicate the origins of the P. falciparum isolates. Purple, Africa; green, Asia; red, Central and South AmericaBack to article page
