Crested Gecko Morphs: Lilly White, Axanthic & Cappuccino Genetics Explained

The Crested Gecko (Correlophus ciliatus) morph market has expanded with verified Mendelian genetic mutations.

Here is an overview of the key documented traits:

1. Lilly White (Incomplete Dominant)

• First developed by Nick Suprowicz at Lilly Exotics.
• Visual Lilly Whites express bright white dorsal and lateral patterns, creamy crowns, and raised dorsal scales.
• Crucial Breeding Warning: Super Lilly White (homozygous) is a lethal genotype resulting in embryonic or post-hatch mortality. Never breed Lilly White to Lilly White.

2. Axanthic (Simple Recessive)

• Suppresses all yellow and red carotenoid pigments, leaving stark charcoal black and clean silver-white tones.
• Simple recessive inheritance: both sire and dam must carry the allele to produce visual Axanthics.

3. Cappuccino & Super Cappuccino

• An incomplete dominant gene producing a velvety coffee-brown hue.
• Pairing Cappuccino to Cappuccino produces the Super Cappuccino (the 'Lucy'), an all-white gecko with solid dark eyes.
• Pairing Cappuccino to Lilly White produces the Frappuccino.
