Phylogenetic reconstruction of identified Aplysia rhodopsin G-protein coupled receptor-like gene sequences. Subfamily type a (red) type b (blue) and type c (green). The trees are based on the bayesian inference reconstruction combined with the RAxML results. The numbers at the branches correspond to posterior probabilities (>75) and congruent bootstrap probabilities (>60, with exceptions), respectively. (a) Unrooted tree without non-Aplysia sequences. (b) Phylogram with non-Aplysia sequences included.
