Wow, that's definitely the first time I've seen that. Perhaps it is a developmental genetic anomaly similar to having different colored eyes. Keep us updated on the split gecko.
Two-Faced Geckobaby. That looks like we have a Patty Stripe Jungle mix with a clear break in the middle
Do the parents have Murphy Patty genes in them?
This is soooo cool.
however im not sure you can class it as a Gynandromorph in this instance due to the fact that leos don't have a specific colourations to distinguish males from females.
the only way to tell would be to take DNA samples from each of the sides and test them?
