Arctic Ultramel

Under review

Includes Frost, which is currently under review by the hognose community. It's in the Public Morph Guide so you can browse it — the look is real and well documented; how it inherits is still being worked out.

The genetics

Albino

Recessive

Albino is a recessive, amelanistic mutation in which melanin is absent entirely. The normal blotched pattern stays visible but loses all black pigment, leaving red, orange, or yellow tones with red eyes.

Frost

Under reviewRecessive

Recessive — an animal must inherit two copies for it to show visually. A single copy is a hidden 'het' carrier.

This gene is currently under review by the hognose community.

Hypo

Recessive

(Evans/Dutch Hypo) — Hypo is a recessive, true hypomelanistic mutation that reduces rather than eliminates melanin. Dorsal blotches come out brighter and more saturated — often orange instead of brown — while the dark eyes are retained.

Arctic

Incomplete Dominant

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 Ultramel Arctic

  • Two copies of Albino — recessive, so it only shows when paired up.
  • Two copies of Frost — recessive, so it only shows when paired up.
  • Two copies of Hypo — 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.
