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.

Arctic x2

Incomplete Dominant

Superarctic is the two-copy (super) form of the Arctic gene — not a separate gene. It produces a stronger, more dramatic expression of the Arctic look: brighter, cleaner, often with very strong black-and-white contrast. It occurs when a hognose inherits Arctic from both parents.

What makes a Sub Zero

  • Two copies of Albino — recessive, so it only shows when paired up.
  • Two copies of Arctic — the 'Superarctic' super form.

This describes the genetics of the animal itself — not the odds from a pairing. Outcome odds are the Genetics Calculator's job.
