Fig. 4

The proportion of Pvama1 haplotype variations observed in different geographical populations. The size of the pie 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 of each pie represents different country. The torso of the haplotype network is shown with light red shadow. Abbreviation: H21, haplotype 21
