Figure 1From: Phylogenetic analysis of mitochondrial protein coding genes confirms the reciprocal paraphyly of Hexapoda and CrustaceaNucleotide tree, 1st and 2nd codon positions. Numbers at nodes indicate posterior probabilities (×100). Vertical lines indicate monophyletic orders (thick) and families (thin). Lower-case order-level taxonomic names indicate non-monophyletic taxa.Back to article page
