Tang et al. (2023) "investigate color morph-enriched Asian vine snakes (Ahaetulla prasina), to explore the mechanism underpinning color variations. Transmission electron microscopy imaging and metabolomics analysis indicates that chromatophore morphology (mainly iridophores) is the main basis for differences in skin color."
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 SMARCE1.
