I think it's just a normal but before I buy a male and female I'd like to know what I'm getting. Local pet store that doesn't know what morph. Age about Obe years old.
Mack Snow x HIgh Yellow will give you 50% Mack Snow & 50% Normals
Mack x Mack will give you 25% Mack Snow, 25% Super Snow & 25% normals
Im sure about the first pairing and pretty sure about the second. Someone will correct me if Im wrong.
If you don't know the morph, then I feel it's best not to breed it. In doing so, you may save yourself from a whole load of genetic surprises and messes in the offspring. That gecko, both of your geckos actually, could possibly be carrying hidden hets which could or could not manifest in the offspring.
If you are starting to get serious about breeding, then it's best to refrain from pet store geckos and instead invest in geckos from breeders, where you can inquire about the morphs of the parents, etc. and get a clear genetic background.
