Fire Yellow Belly Ball Python
One animal carrying both genes. Each one is inherited separately, so this combination is made by bringing them together rather than being a gene of its own.
The two genes
- Yellow Belly
- co-dominant
- Subtle: cleaner belly and flame markings on the flanks. Two copies produce a cream animal with a faint dorsal line.
How one is made
Both genes have to come together in the same animal. The pairing that does it most directly is Fire × Yellow Belly, which works out every outcome and its odds.
