Fig. 3From: Genetic interrelationships of North American populations of giant liver fluke Fascioloides magna Haplotype network of Fascioloides magna populations obtained in TCS. Each haplotype is represented by a circle scaled according to the number of specimens. Empty circles along the mutation pathways represent putative unsampled haplotypes. Codes for enzootic regions, US states and Canadian provinces are explained in Table 1 Back to article page
