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 TYRP1.
- Tyrp1 is the mendelian determinant of the Axolotl (Ambystoma mexicanum) copper mutant. — Sci Rep 2024
