Corn Snake morph
Corn Snake (Pantherophis guttatus)
Reduced black pigment
Reduces melanin expression without eliminating it. Animals display brighter, more vivid coloration: orange-red background is more intense/cleaner, dark pattern elements (saddle outlines, belly checks) are reduced or lightened, and the overall appearance is "cleaner" and brighter than wild-type. Hypomelanistic corn snakes retain some dark pigment but it is visibly reduced. Saddle outlines appear brownish rather than dark gray-black. The belly checkered pattern is reduced or absent in the center rows. DISTINCT from Sunkissed (Sunk locus), which produces a similar hypo-like appearance but is a separate independent locus. Hypo x Sunkissed cross produces wild-type-looking double het offspring (not visual hypos), confirming independence. Some older literature conflates the two. Participates in the Ghost combo morph (Hypo + Anery A) and Amber (Hypo + Caramel).
How to identify it: Brighter orange-red background with reduced dark pigment. Saddle outlines brownish/reduced. Belly pattern faded or reduced in center. Overall "clean" appearance. Cannot reliably distinguish from Sunkissed without test breeding.
Hypomelanistic follows a recessive inheritance pattern, carried on the Hypomelanistic allele (locus Hypo).
Because Hypomelanistic is recessive, an animal needs two copies of the allele to show the trait visually. An animal with a single copy is called het hypomelanistic (heterozygous). A het animal looks normal but carries the gene, so pairing two het hypomelanistic animals produces, on average, one in four visual hypomelanistic offspring.
Amber
Hypomelanistic + Caramel combination. Produces warm amber/golden coloration.
Creamsicle
Amelanistic + Hypomelanistic combination. Produces a bright cream-orange to light orange animal.
Ghost
Hypomelanistic + Anerythristic Type A combination. Produces a muted, ghostly gray-green to silver appearance.
