Black Pastel Spider 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 findings on these genes
Black Pastel. Animals homozygous for this gene are widely reported in breeder records to show structural defects including kinked spines and jaw abnormalities.
Spider. Animals carrying this gene are widely documented to show a neurological head wobble, ranging from barely detectable to severe. It is associated with the gene itself rather than with husbandry, and every animal carrying it is considered affected to some degree.
The two genes
- Black Pastel
- co-dominant
- Darker and more contrasted, with the pattern reduced and the browns pushed toward black.
How one is made
Both genes have to come together in the same animal. The pairing that does it most directly is Black Pastel × Spider, which works out every outcome and its odds.
