Crested Gecko morph
Crested Gecko (Correlophus ciliatus)
Homozygous Harlequin morph (HQ/HQ) displaying maximum flame/pattern concentration. Extreme pattern coverage approaching 80%+ of body. Pattern connects dorsal to lateral regions and can form full saddles. Also called Extreme Harlequin. NOTE: "XXX" is a marketing descriptor coined by Matt Parks (Pangea Reptile) for phenotypically extreme Harlequin animals, not a genetic designation. XXX animals are not necessarily proven homozygous.

Concentrates dorsal pattern into flame-like or high-contrast patches. Heterozygous animals show intermediate pattern concentration; homozygous show maximum concentration and contrast. Interacts with Tiger to create visible pattern breaks and "portholes." Antagonistic with Empty Back.
How to identify it: Harlequin animals show concentrated pattern flames, especially on dorsum. Super Harlequin shows maximum flame concentration.
Super Harlequin follows a incomplete dominant inheritance pattern, carried on the Harlequin allele (locus HQ).
Brindlequin
Five-allele combination requiring Yellow Base + White Pattern + Harlequin + Pinstripe + Tiger at specific expression ratios to create tri-color brindle pattern.
