Skin colour (FOXD3) Robe Rocket Frog
Goutte et al. (2025) "investigate the genetic architecture of GCP [green colour polymorphism] in a radiation of African grass frogs endemic to the Ethiopian Highlands (12 species; genus Ptychadena ). Within this radiation, four species ( Ptychadena robeensis , Ptychadena levenorum , Ptychadena erlangeri, and Ptychadena nana ) form a monophyletic clade and share the same green/brown polymorphism (Goutte et al., 2021). Using whole-genome resequencing data, we identify and characterize the GCP locus [FOXD3] and show that this genomic region is evolving under long-term balancing selection, re
How it inherits
- One copy
- One copy is enough to see it.
- Two copies
- Two copies look the same as one.
Skin colour (FOXD3) × Skin colour (FOXD3)
Four ways the two can meet.
- Skin colour (FOXD3)75%
- 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.
What this rests on
A peer-reviewed paper identifies the variant behind this morph in the gene FOXD3.

What happens if you breed it
Every pairing involving Skin colour (FOXD3), worked out gene by gene — including what the clutch can be and anything documented about the animals it produces.
