What Ivory looks like

Homozygous or compound het at Yellow Belly locus. Near-white with subtle yellow/lavender wash. Super form of the Yellow Belly complex.

Multi-allele locus with subtle heterozygous expression and dramatic super forms. Yellow Belly (het): subtle expression. Slightly cleaner pattern, enhanced yellow tones, distinctive "flames" along the belly edge, and a mostly unmarked yellow belly (hence the name). Specter: very similar to Yellow Belly, sometimes considered the same allele. Gravel: subtle dusty/granite appearance. Asphalt: subtle dark modifier. Spark: similar to Yellow Belly. Homozygous or compound het forms: Ivory (Super Yellow Belly) is a near-white animal with slight yellow wash and lavender highlights. Super Stripe (Yellow Belly x Specter or similar) produces dorsal striping pattern.

How to identify it: Yellow Belly: clean belly, subtle flames on lower sides, slightly enhanced yellows. Very subtle as a single gene. Ivory (super form): near-white with lavender/yellow wash, no pattern. Super Stripe: dorsal stripe pattern.

How Ivory is inherited

Ivory follows a incomplete dominant inheritance pattern, carried on the Yellow Belly Complex allele (locus YB).
