Arctic Swiss Chocolate
The genetics
Swiss Chocolate
Swiss Chocolate is a recessive, hypermelanistic mutation that increases melanin production, concentrated most heavily on the head. Hatchlings are born dark and stay that way, producing a rich chocolate-brown snake — similar to Sable but darker and warmer in tone.
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 Chocolate Arctic
- Two copies of Swiss Chocolate — 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.
