Albino Leucistic Black Rat snake

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

Albino: recessive; No black pigment, leaving a white and yellow animal with red eyes.
Leucistic: recessive; Pure white with dark eyes — not an albino, because the eyes carry pigment.

How one is made

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