I've often heard that issue with cresties before. In fact, that's probably the #1 thing that has kept me from pairing mine up. It's the responsible thing to do in the end.
Hello and welcome to GeckoTalk!
Kudos to you and your wife on the adoption!
I'm not positive how the phenotype inheritance works with cresties but maybe one of our resident crestie breeders can chime in...
Anyone going to the Reptile Super Show tomorrow at the Los Angeles County Fairgrounds?
I will be there! If any of you would like to meet up, send me a PM or reply below! It's going to be a great time!
