Leopard Gecko Morphs Calculator (Free & Easy to Use)
Want to know what morphs your leopard gecko babies might have? Use our free Leopard Gecko Morphs Calculator to get instant genetic outcome predictions based on parent traits.
Just select the genes of the male and female geckos — recessive, dominant, co-dominant, and polygenic — and the tool will show you the possible morphs and chances.

Recessive: Trait only shows if both parents have it. If only one does, babies are “het” (carriers).
Co-Dominant: One parent = visible. Both = some babies may show a stronger “super” version.
Dominant: One parent is enough. Babies will definitely show the trait.
Line-Bred (Polygenic): Passed by selective breeding. May appear in babies if present in parents, but no exact %.
Co-Dominant: One parent = visible. Both = some babies may show a stronger “super” version.
Dominant: One parent is enough. Babies will definitely show the trait.
Line-Bred (Polygenic): Passed by selective breeding. May appear in babies if present in parents, but no exact %.
What This Calculator Does:
- Predicts offspring morphs based on selected traits
- Handles recessive, dominant, and co-dominant gene logic
- Shows line-bred traits like Tangerine or Carrot Tail
- Works instantly with no login, no signup
How Leopard Gecko Genetics Work (Short Version)
- Recessive traits only show if both parents carry the gene.
- Dominant traits will show up even if only one parent has it.
- Co-dominant traits can result in “super” forms if both parents carry it.
- Polygenic traits (like Tangerine, Bold Stripe) may show up but aren’t guaranteed.
Examples You Can Try:
- Tremper Albino x Normal = 100% het Tremper Albino
- Blizzard x Blizzard = 100% Blizzard
- Mack Snow x Mack Snow = Super Snow chances
- Tangerine + Carrot Tail = possible colorful babies
