Butter Pastel 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

Butter: co-dominant; Lighter, cleaner brown with the pattern washed out and the dark edging reduced. Two copies give a white animal with blue eyes.
Pastel: co-dominant; Brighter yellows, faded pattern, and lighter head. Two copies give a paler animal still.

How one is made

Both genes have to come together in the same animal. The pairing that does it most directly is Butter × Pastel, which works out every outcome and its odds.
