New to Ball Pythons, need help identifying my albino

[ascended]

Well it helps see the pattern for pattern changing morphs like mahogany. Im not sure yellowbelly has enough difference to be enhanced by UV.
Some all white snakes with another morph can also show up some pattern to a lesser extent with UV too.
To learn the morph patterns I check morphmarket daily and also for more accuracy look up morphs on Morphpedia
Regarding the Bananas, this discussion was interesting;-

How to tell if your Blue Eyed Leucistic is also Banana

We discovered a way to tell if your BEL is carrying Banana. I breed a lot of Banana BEL to make my Blue Eyeds. Previously we didn’t think there was a way to tell if they were carrying the Banana gene. One of my employees who IDs and sets up babies discovered this method. I thought it was interesting and wanted to share it with you guys. It is performed by illuminating behind the eyes. If they glow red they are Banana and if not they aren’t.
