Arabesque Kahl Albino 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
How one is made
Both genes have to come together in the same animal. The pairing that does it most directly is Arabesque × Kahl Albino, which works out every outcome and its odds.
Worth knowing
Kahl Albino. There are two separate albino lines in boas, Kahl and Sharp, and they are different genes. A Kahl albino bred to a Sharp albino produces normal-looking young — each carrying one copy of each gene, and not one of them albino. Check which line an animal comes from before pairing it.
