Axanthic

What Axanthic looks like

No yellow/red pigment

Reduces or eliminates xanthophore pigment (yellow and red pigment). Homozygous Axanthic animals display a silvery-gray to blue-gray coloration with reduced or absent yellow and orange tones. The typical warm orange-brown of wild-type is replaced by cool gray tones. Dark pattern elements (saddle marks) are retained but appear in contrasting dark gray to black against the silvery base. Melanin is fully retained. Eyes remain dark, and the animal can appear quite striking in its silver-gray and black patterning. Axanthic is independent from Lavender (the two produce distinct phenotypes and complementation crosses produce wild-type-appearing double hets). When combined with Albino, produces the Snow morph, as the absence of both melanin and xanthophores results in a near-white animal.

How to identify it: Silvery-gray to blue-gray background; dark gray to black saddle marks; dark eyes. No yellow, orange, or warm tones. Distinguishable from Lavender by the cooler, more silver-gray (vs. gray-lavender/purple) base color and by complementation testing. Hatchlings may appear more distinctly patterned; the silver quality intensifies with age.

How Axanthic is inherited

Axanthic follows a recessive inheritance pattern, carried on the Axanthic allele (locus AXAN).

Combo morphs with Axanthic

• Snow

  Double recessive Albino + Axanthic. The absence of melanin (Albino) and yellow/red pigment (Axanthic) together produce a near-white to white animal with soft pink tones and red/pink eyes. One of the most visually clean and sought-after hognose combos. The Snow is to western hognose what Snow is to corn snakes and ball pythons. A foundational "clean" white combination.

• Arctic

  Double recessive Axanthic + Lavender. Combining the yellow/red reduction of Axanthic with the grey-lavender shift of Lavender produces a very pale, icy animal with minimal warm pigmentation and soft lavender-gray tones. The result is an ethereal, cool-toned animal evoking an arctic appearance. Genetics modeled as Axanthic + Lavender; exact community definition varies.

• Axanthic Anaconda

  Homozygous Axanthic + heterozygous Anaconda. Combines the silver-gray coloration of Axanthic with the reduced pattern of Anaconda. Produces a strikingly clean silver-gray animal with dramatically reduced black-and-dark-gray dorsal pattern. The cool tones of Axanthic over a reduced Anaconda pattern create a sleek, minimalist appearance.

• Snow Anaconda

  Homozygous Albino + homozygous Axanthic + heterozygous Anaconda. The Snow base (near-white from combined Albino and Axanthic) with Anaconda's pattern reduction produces an animal that is essentially white with minimal to no visible pattern. Red/pink eyes from Albino. Considered one of the premium combinations in the hognose morph market for its near-patternless white appearance.
