What is the Leopard Gecko Morph & Genetics Calculator?
The Leopard Gecko Morph & Genetics Calculator predicts possible offspring morphs from parent leopard gecko genetics. Understanding likely outcomes helps breeders set expectations and avoid pairing combinations that could carry unwanted or harmful traits.
Leopard geckos generally live 15-20 years when they are well looked after. They are an insectivore, so their nutritional needs shift with age, size and activity. A single adult needs at least a 90x45cm floor area with a warm hide around 32C, a cool hide, and a humid hide to help shedding. Belly heat from a mat with a thermostat matters more than overhead heat. The usual suspects for this species are metabolic bone disease, retained shed on toes and eyes, impaction from loose substrate, so any noticeable change is worth following up.

How does the Leopard Gecko Morph & Genetics Calculator work?
The prediction uses a simplified model of the most influential genes for the trait in question. Real genetics can involve additional modifier genes not captured here, especially for complex or rare morphs. The math is only as good as what you feed it, so an accurate, recent input matters more than the formula itself.
Factors that matter
- The genotype (not just visible appearance) of both parents, which isn't always knowable without testing
- Whether either parent carries a recessive trait that isn't visibly expressed
- Modifier genes not included in this simplified model, which can shift real-world results
- Litter or clutch size: since probabilities describe averages across many offspring, not a single guaranteed outcome
How do you use the Leopard Gecko Morph & Genetics Calculator?
- Pick your parent A — Albinism (Normal, Albino)
- Pick your parent B — Albinism (Normal, Albino)
- Pick your parent A — Enigma (Normal, Enigma)
- Pick your parent B — Enigma (Normal, Enigma)
- Press Calculate, then read the result alongside the sources listed below
If the result looks wrong, check your inputs before you worry. Entering weight in the wrong unit is easily the most common reason a figure looks off.

Before you rely on this
This calculation assumes a healthy adult leopard gecko with no complicating conditions. Pregnancy, recovery from illness, medication and significant age at either end of the scale all change what is appropriate. When in doubt, the safest move is to take the number to a vet and ask whether it fits your particular animal.
