Leopard Gecko

Eublepharis macularius

Three independent recessive albino lines (Tremper, Bell, Rainwater) form the spine of the genetics. Layered against incomplete-dominant Mack Snow, recessive Eclipse, recessive Murphy Patternless, recessive Blizzard, and well-documented polygenic line-bred traits (Tangerine, Hypo, Super Hypo, Carrot Tail, Bold, Stripe). Lemon Frost homozygotes develop iridophore tumors (Guo et al. 2021 PLOS Genetics). Enigma carries Enigma Syndrome (variable neurological symptoms documented across multiple care references).
