Corn Snake morph
Corn Snake (Pantherophis guttatus)
Yellow/brown coloration
Shifts the pigmentation toward warm yellow-caramel tones. Red pigment is replaced by yellow-amber or caramel coloration. Dark pigment (melanin) is retained but may appear brownish rather than black. Background shifts from the typical orange-red of wild-type toward golden-yellow and caramel. Saddle marks typically appear brown. When combined with Amelanistic, produces the Butter morph (Amel + Caramel): a warm yellow animal with no dark pigment, often cream/yellow with very soft pattern elements.
How to identify it: Golden-yellow to caramel background; saddle marks brown rather than the typical dark gray/brown. Lacks the vibrant red-orange of wild-type. Distinguishable from Hypo by the yellow/caramel rather than orange tone of the background.
Caramel follows a recessive inheritance pattern, carried on the Caramel allele (locus Cara).
Because Caramel is recessive, an animal needs two copies of the allele to show the trait visually. An animal with a single copy is called het caramel (heterozygous). A het animal looks normal but carries the gene, so pairing two het caramel animals produces, on average, one in four visual caramel offspring.
Amber
Hypomelanistic + Caramel combination. Produces warm amber/golden coloration.
Butter
Amelanistic + Caramel combination. Produces a warm butter-yellow to cream-yellow animal with no dark pigment.
