I want to chime in as a person that has had this happen to him. Yes I have had the pleasure of having a dirty male.
The mom looks Bell. I am 99.99999% sure of that. The baby also looks bell and again I am pretty sure on that.
You are doing everything you can to learn the genetics of your animals. This is not your fault. It is the fault of people taking shirt cuts IMO. Wanting to get the tremper combos (enimga, Eclipse, Patty, and others) into the bell and rainwater lines.
I feel your pain. And it sucks that it has happened to you. But trust me. YOu want to find out sooner then later.
Keep the love for the geckos. as it is not their fault.
