Fig. 1From: Genetic diversity and selection of three nuclear genes in Schistosoma japonicum populationsHaplotype networks for Schistosoma japonicum based on the coding region of SjIpp2 (a), SjFabp (b) and SjT22.6 (c). Each color represents a locality. The distance between two haplotypes corresponds to the numbers of substitutions. Abbreviations of the geographical localities are shown in Table 1 Back to article page
