Fig 2. Summary of sister-group relationships based on the simultaneous analysis of 18S and 28S rDNA regions using parsimony as the optimality criteria for rhinebothriideans.

Division between sets of synapomorphies indicates transformations from 18S and 28S rDNA, respectively. For each base pair, black cells represent unambiguous unique synapomorphies, red cells represent unique homoplastic synapomorphies, and blue cells represent non-unique homoplastic synapomorphies (see 45). Numbers below each cell represent alignment position for respective gene regions.
