A lot of morphs do seem to have issues getting the pattern all the way down from the spine onto the belly. Surprised that specter isn't more like yellow belly with a clear belly. I also thought cinnamon/black pastels were always clear belly but then I've only owned two of those that weren't combos with some other gene (both were clear belies). Chocolates tend to have at least normal to more than normal belly pattern and I understand sable does too. Hard to tell on albinos but presumably them and hypos would have belly pattern if they had the dark pigment to show it and suppose the same goes for caramel, ultramel, crider, and candy but I really have no idea on those last four color mutations, just hadn’t heard of them having a pattern factor and assume there wouldn’t be enough dark pigment to see if there is a belly pattern or not. I've not yet owned any of the recessive axanthic but hadn't heard of them having anything other than normal belly pattern. Everything else I can think of right now is in the clear belly list.
