Fig. 2 in Molecular and morpho-anatomical assessment of the family Dorididae (Mollusca, Nudibranchia) in the Mediterranean and North-East Atlantic
Fig. 2. Bayesian phylogenetic tree of Dorididae Rafinesque, 1815 based on the concatenated alignment of COI, 16S, and H3 markers. Posterior probabilities and bootstrap support values are shown above and below branches, respectively. The outgroup used to root the tree was the genus Aphelodoris Bergh, 1879. Green dots indicate nodes with maximum branch support in both analyses. The scale bar indicates substitutions per site. Names of the sequences downloaded from GenBank have not been modified, yet taxa that may belong to a different identity are specified between quotation marks. Specimens sequenced in this study are highlighted in bold.
