Corn Snake Genetics Guide — Morph Crossing & Trait Fixation

Corn snakes have the most thoroughly understood morph genetics of any pet reptile, with simple recessive inheritance making them ideal for learning breeding genetics.

Key Morphs (All Recessive)

Amelanistic: No black pigment. Bright red, orange, and white. Most popular morph. Anerythristic: No red/orange pigment. Gray and white monochrome. Snow: Amelanistic + Anerythristic combo. White to pale pink. Lavender: Purple-tinted gray. Relatively new morph.

Punnett Square Example

Amel x het Amel = 50% Normal (het Amel) + 50% Amelanistic. het Amel x het Amel = 25% Normal + 50% Normal het Amel + 25% Amelanistic.

Creating Combo Morphs

Combine two+ morph genes through planned crosses. F1 generation carries both genes heterozygously. F2 produces the combo morph at 1/16 probability.
