Axanthic

What it looks like

Axanthic is recessive. With two copies the gecko has no yellow or red pigment, so it shows in greys, blacks and paper white.

This page shows Axanthic drawn from its genes. For the written reference, inheritance tables and breeder notes, see the crested gecko morph guide on ReptiDex.

In depth

Removes yellow and red coloration, creating grey/black phenotypes. Recessive inheritance. Homozygous animals lack xanthophore pigments. Synergistic with Pinstripe to create strong paper-white pattern expression.

How to spot it

Axanthic animals lack yellow/red colors, appearing grey, black, or desaturated. Combined with Pinstripe creates strongest paper-white.

Where it came from

Axanthic was identified as a color reduction trait affecting xanthophores.

How it is inherited

Recessive: it takes two copies to show.

Written as x+ and x

Axanthic + Pinstripe produces one of the strongest paper-white expressions in the species. Recessive confirmed. Source: Foundation Genetics Part 1.

Beside other genes

• Axanthic and Pinstripe strengthen each other

  Axanthic + Pinstripe creates strongest paper-white pattern expression in species. Removal of xanthophores enhances white pattern.

Morphs it takes part in

• Axanthic Phantomdifficult

  Deep monochrome grey to black coloration with no warm tones. Strong melanin presence without xanthophore interference.

  Needs Axanthic, Phantom.

• Charcoaltakes some work

  Uniform charcoal to dark grey coloration. Reduced or absent dorsal pattern from Empty Back. No warm orange or yellow tones. Cool grey throughout.

  Needs Axanthic, Empty Back.

• OG Noirdifficult

  Silver-grey to near-white body with no warm pigmentation. Cool, achromatic coloration throughout. High-contrast pattern elements remain in grey tones. One of the most visually dramatic double recessive combinations.

  Needs Axanthic, Phantom.
