Figure 1.
Phylogenetic relationships of C. intestinalis subpopulations. Consensus sequences for the col5a1 interval, obtained for each of the six subpopulations analyzed in this study, were used to calculate the population tree. Subpopulations are defined by their collection locations, as in Table 1. The size of the circle surrounding each subpopulation is proportional to the heterozygosity of that subpopulation.
