Traits
Codominant(1)
- Tessera
Co-dominant pattern trait. Visual Tessera × Normal produces ~50% Tessera; Super Tessera (homozygous) is a distinct phenotype with full striping and reduced lateral pattern. Some early references list Tessera as 'dominant'; the codominant classification matches current breeder consensus.
Recessive(17)
- Amelanisticalso: Amel, Albino
- Anerythristicalso: Aner, Anery, Anery A
Type I anerythristic (the original Anery line). Distinct from Charcoal, which is Anery B at a separate locus — they are NOT the same gene; Anerythristic × Charcoal offspring are double-het, not visual.
- Lavender
- Caramel
- Bloodred
Some breeders argue Bloodred ≡ Diffused (same locus). The catalog keeps them as separate trait rows pending consensus.
- Charcoalalso: Anery B
Type II anerythristic locus, hobby-named 'Charcoal'. Distinct from regular Anerythristic (Anery A) — different gene; Charcoal × Anerythristic offspring are double-het, not visual.
- Diffused
Some breeders argue Diffused ≡ Bloodred (same locus). The catalog keeps them as separate trait rows pending consensus.
- Stripe
- Motley
- Palmetto
- Scaleless
- Hypo
Umbrella name for hypomelanistic recessives in corn snakes. Multiple distinct lines exist (Hypo A, Hypo B, Lava, Christmas, Ultra) at different loci — they are NOT interchangeable for breeding. The catalog ships the umbrella; specific lines can be added when users need to distinguish them in pairings.
- Sunkissed
Hypomelanistic-line recessive at a separate locus from the umbrella Hypo. Sunkissed × Hypo offspring are double-het (each parent's allele only), not visual.

Visual compound of Amelanistic + Anerythristic — multi-locus. Calculator emits 'outcomes vary' rather than fake single-locus predictions.
