Fig. 2From: Evolution of the Plasmodium vivax multidrug resistance 1 gene in the Greater Mekong Subregion during malaria eliminationMinimum spanning network for global P. vivax parasite populations. The size of the pies reflects the frequency of a particular haplotype. The lengths of the lines connecting the pies, measured from their centers, are in proportion to the number of base pair substitutions separating the haplotypes. Color represents different countries. Haplotypes observed in different continents are encircledBack to article page
