Well I got into it, and it easily became overwhelming, to be real honest. Been a while since I've done punnetts. Plus, I'm no snake breeder, so I'm not too terribly experienced on what's dominant, what's recessive, etc.
From looking around, it seems the Paradigm morph is a double heterozygous gene, snow is a double recessive(homozygous), and sharp is a recessive(homozygous).
Since two of those are doubles, it's going to be a pretty large punnett square, hence why I said it quickly became overwhelming, lol...
This may help you with just starting out with punnetts:

Here's the information I used on the morphs:

Here's a guide from NERD:
New England Reptile Distributors, designer Ball Pythons, Reticulated Pythons, and much more!
And here's a calculator where you can add traits/genes, and input variables for them to get a quick calculation and estimation of outcome.
