Cinnamon Ultramel 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.
Documented health finding on one of these genes
Cinnamon. Animals homozygous for this gene — Super Cinnamon — are widely reported in breeder records to show structural defects including kinked spines and shortened, misaligned jaws.
The two genes
How one is made
Both genes have to come together in the same animal. The pairing that does it most directly is Cinnamon × Ultramel, which works out every outcome and its odds.
