Bell Albino Marble Eye Common Leopard Gecko
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 Bell Albino × Marble Eye, which works out every outcome and its odds.
Worth knowing
Bell Albino. One of three separate albino strains, not compatible with Tremper or Rainwater. Pairing across strains yields no albinos.
