The procedure is: Create a punnet square to find the percent chances of each gamete combination. There are hundreds of websites available through Google that can walk you through this step-by-step for any combination you want. Then multiply those percentages by the percent "Het". For instance, if you have a Het to Het breeding, you get a 25%, 50%, 25% ratio, then you multiply these percentages by the 50% or 66% percent Het of the adults. It is one of the rare combinations of family and population genetic statistics necessary to know when breeding Ball Pythons.

And I will say it again: The percentages you get from a punnet square are the odds of the GAMETES sorting to create that combination. They are NOT the percentage of a certain individual you get in a clutch of eggs. Those ratios only prove out phenotypically over hundreds and hundreds of eggs, not just one clutch. In one clutch, you are just about as likely to get all normals as all morphs. Frustrating, I know.
