Blizzard Enigma 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.
Documented health finding on one of these genes
Enigma. Animals carrying this gene are widely documented to show neurological signs — circling, star-gazing, loss of balance, and difficulty targeting food — commonly called Enigma Syndrome. It is associated with the gene itself rather than with husbandry, and severity varies between animals.
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 Blizzard × Enigma, which works out every outcome and its odds.
