Anerythristic Type II Leopard Red-Tailed Boa Constrictor
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
- Anerythristic Type II
- recessive
- A separate anerythristic line, often browner than Type I and holding more pattern.
How one is made
Both genes have to come together in the same animal. The pairing that does it most directly is Anerythristic Type II × Leopard, which works out every outcome and its odds.
