Orange/red Common Wall Lizard

How it inherits
- One copy
- One copy shows nothing at all. The animal looks ordinary and is called a carrier, or “het”.
- Two copies
- Two copies, one from each parent, are needed before it appears.

A pale box is an animal that shows the morph. These are the odds for each egg on its own, not a promise about a clutch.
What this rests on
A peer-reviewed paper identifies the variant behind this morph in the gene SPR.
- Regulatory changes in pterin and carotenoid genes underlie balanced color polymorphisms in the wall lizard. — Proc Natl Acad Sci U S A 2019
- Pterin-based pigmentation in animals. — Biol Lett 2021
- Physiological phenotypes differ among color morphs in introduced common wall lizards (Podarcis muralis). — Integr Zool 2024
What happens if you breed it
Every pairing involving Orange/red, worked out gene by gene — including what the clutch can be and anything documented about the animals it produces.
