I agree that if one is curious what a potential combo would look like, the best way to find out is to make it rather than asking on a forum (unless it has already been made). However, it takes rather a long time, and isn't necessarily very practical.
In some cases, we have no idea why a morph creates the look it does, and it is very hard to predict what a combo will look like.
In the case of the axanthic genes, we know pretty much exactly what they do, so it is much easier to predict what an axanthic combo will look like. Specifically, the axanthic gene reduces (pretty much eliminates) the production or expression of the yellow pigment cells, which I believe are called xanthospores. So, in a snake that already shows very little yellow, reducing or eliminating it should have very little effect.
That is not to say it is impossible that there will be an unexpected outcome, just highly unlikely. It is even possible that one of the 3 known axanthic genes would create an interesting effect, while the other 2 behave in the way we expect in this combo. So go ahead and make all 3 versions of it if you want. Personally, I'd rather use my breeding efforts in a direction likely to make something a little more interesting than an axanthic super cinnamon that may be indistinguishable from a regular super cinnamon.
dude you just had to say something mr.know it all the second ...![]()
