Figure 2.

Single maximum likelihood tree with values from the separate bootstrap analysis shown at internal nodes when 70% or greater. Analysis of nucleotide sequences for 12 protein-coding genes with third codon positions included (11,784 characters) for 41 nematode mitochondrial genomes inferred using RAxML (see methods for analysis details). The classification of De Ley and Blaxter [12,13] is used to label each tree figure.
