The genetics
Axanthic
Axanthic is a recessive mutation that removes yellow (xanthin) pigment while leaving melanin intact. The result is a gray, black, and white snake that keeps its normal pattern and dark eyes but loses all warm coloration.
Lavender
Lavender is a recessive, tyrosinase-positive (T+) form of albino. It produces a soft gray-lavender body with a purple tongue and eyes; hatchlings often carry a reddish tint that fades to lavender-gray with age.
Arctic
Arctic is an incomplete-dominant gene that tends to brighten, clean up, and cool the overall appearance of a Western Hognose. Arctic animals often show a lighter base color, sharper contrast, cleaner pattern, brighter coloration, white outlines around pattern elements, and speckling/flecking compared to non-Arctic animals.
What makes a Mercury Arctic
- Two copies of Axanthic — recessive, so it only shows when paired up.
- Two copies of Lavender — recessive, so it only shows when paired up.
- One copy of Arctic — the single-gene Arctic form (incomplete dominant).
This describes the genetics of the animal itself — not the odds from a pairing. Outcome odds are the Genetics Calculator's job.
