Figure 7

T. cystophora opsins can be classified into two groups, a probable more ancient Tc-group 1 opsin, with a broader expression pattern, and Tc-group 2 – rhopalium-specific opsins. The size and shade intensity of the symbols corresponds with the level of expression. Green coloured box and branches represent rhopalia specific Tc group 1A opsins. Purple coloured box and branches represent male specific Tc group 1B opsins. Red coloured box and branches represent rhopalia specific Tc-group 2 opsins.
