What GHI looks like

Heterozygous GHI. Darker coloration with deep golden-brown and black tones, iridescent sheen. Patternless belly.

Darkens and intensifies coloration with a distinctive iridescent sheen. Heterozygous (GHI) produces a darker animal with deep golden-brown and black tones, often with an oily or iridescent quality to the scales. Homozygous (Super GHI) is extremely dark, near-solid black with intense iridescence. GHI is highly valued as a building-block gene in dark or melanistic combos.

How to identify it: GHI (het): darker overall coloration, deep golds and blacks, iridescent/oily sheen on scales, patternless belly. Super GHI: extremely dark, near-solid black with strong iridescence.

How GHI is inherited

GHI follows a incomplete dominant inheritance pattern, carried on the GHI (Gotta Have It) allele (locus GHI).
