Yellowbelly series Ball Python
Dao et al. (2023) report that several color phenotypes in pet [ball pythons] animals are associated with putative loss-of-function variants in the gene encoding endothelin receptor EDNRB1: (1) frameshift variants in EDNRB1 are associated with conversion of the normal mottled color pattern to skin that is almost fully white, (2) missense variants affecting conserved sites of the EDNRB1 protein are associated with dorsal, longitudinal stripes, and (3) substitutions at EDNRB1 splice donors are associated with subtle changes in patterning compared to wildtype."

Offspring odds
No numbers for this one.
No inheritance mode has been recorded for Yellowbelly series, so no offspring odds are given. Guessing one would be worse than saying nothing: a breeder would plan a season on it.
What this rests on
A peer-reviewed paper identifies the variant behind this morph in the gene EDNRB2.
