This is a project I have been working on for quite a while now, this year we finally were about to prove it Co-Dom and have made some amazing animals from it. In the base Hydra it's a pattern mutation, so visually they look different from normals, I have hatched out a couple that were lighter than normals, but for the most part it's all in the pattern, starting at the neck. Once you start combining it with other genes, it becomes both a pattern and color manipulator.
