Percentage on breeding....

Pastel X Pastel ??
Yellowbelly X Yellowbelly?

If I understand correctly, both of these traits are CoDominant. This means the morph is heterozygous for the trait, IE the genotype Pp = Pastel, PP = Super Pastel, pp = Normal. This is the same for Yellowbellies.

So if you have two visible Pastels or Yellowbellies, you will get

25% Normal
50% Pastel / Yellowbelly
25% Super Pastel / Leucistic (Super yellowbelly)

Here is a punnet square outlining how mating to heterozygous (Codominant) parents works.

-----
1.0 normal ball python
0.1 greyband hybrid kingsnake
0.2 crazy cats
1.0 husband

in simple terms one in four should be a visual morph....

Actually since they are co-doms you should get 3/4 visual morphs but only 1/4 supers (statistically)
