Calico Patternless Tuctoo

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

Calico: recessive; Patches of unpigmented skin over the base colour, varying widely between animals.
Patternless: recessive; The orange and white spotting absent, leaving an even blue-grey animal.

How one is made

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