Lemon Frost Common Leopard Gecko
Guo et al. (2021): "Lemon Frost geckos have increased white body coloration with brightened yellow and orange areas. This morph also displays a high incidence of iridophoroma, a tumor of white-colored cells. We obtained phenotype information and DNA samples from geckos in a large breeding colony and used genome sequencing and genetic linkage analysis to localize the Lemon Frost mutation to a single locus."
How it inherits
- One copy
- One copy is enough to see it.
- Two copies
- Two copies produce a distinct animal with its own name — not simply a stronger version.
Lemon Frost × Lemon Frost
Four ways the two can meet.
- Lemon Frost50%
- Super Lemon Frost25%
- Normal25%
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.
Documented health finding. This morph also displays a high incidence of iridophoroma, a tumor of white-colored cells.
What this rests on
A peer-reviewed paper identifies the variant behind this morph in the gene SPINT1.
