Median-joining network of Pvama1 between eight geographically diverse populations.

Haplotypes composed of nucleotide polymorphism in Pvama1 ectodomain with a frequency > 1 were used to create a median-joining network. This network represents the mutational paths connecting Pvama1 haplotypes that may explain the observed sequence diversity. Each node represents one haplotype, node size indicates haplotype frequency and node color corresponds to the country of origin. Line length is proportional to genetic distance.
