Gargoyle Gecko genetics

Gargoyle geckos have no proven single-gene morphs. Every trait Morphpedia lists for them is polygenic, so there's no Punnett square to run — which is the honest answer to the question, and the reason this page has no calculator on it.

So what do you use instead?

Your own hatch records. Pair the same two animals for a few seasons, keep every hatchling logged against its parents with photos and traits, and you learn what that specific pairing produces. For a polygenic species that is not a worse answer than a calculator — it's the only real one.

Why there's no calculator here

  • All 33 traits Morphpedia lists for gargoyle geckos are polygenic. Not most of them — every one. There is no proven recessive, dominant or incomplete dominant gene in this species.
  • Polygenic means several genes acting together, with expression that shifts as the animal grows and is influenced by more than genotype alone. It's why two striking parents can throw a clutch that looks like neither of them, and why a reticulated gecko doesn't reliably make reticulated babies.
  • That isn't a gap in the research so much as how this species works. Any tool quoting you a percentage for a gargoyle pairing is inventing it.
  • What does work is your own records. Pair the same two animals for a few seasons, keep every hatchling's photos and traits against its parents, and you'll know what that pairing actually produces — which is better information than a species-wide average could ever be.

Traits no calculator can predict

MorphMarket Morphpedia classes these as polygenic or structural. They're real traits and they set prices, but they don't sit on a single gene, so no Punnett square predicts them. Anything quoting you a percentage for harlequin or flame is guessing.

What does work for these is records: pair the same two animals for a few seasons and your own hatch data tells you far more than any average could. That's what My Reptile Atlas is for.
