Unrooted consensus tree for 12 natural isolates of C. elegans. The two numbers listed in parentheses next to each node are the percentage of trees among 1000 bootstrap replicates that included all strains distal from CB4856, under Camin-Sokal and Wagner parsimony, respectively. The tree should not be interpreted strictly as a phylogeny due to recombination between strains.
