Leopard Gecko morph
Leopard Gecko (Eublepharis macularius)
Homozygous recessive at the NDBE (Noir Désir Black Eye) locus (ndbe/ndbe). Solid black eyes with reduced dark body pigmentation, producing a clean appearance. When combined with tangerine line-bred genetics, NDBE produces strikingly dark orange to red coloration. The trait appears to interact synergistically with melanistic pathways, enhancing overall color intensity. Discovered from the Gecko Genetics line of tangerines. First recognized around 2015-2016.
NDBE (Noir Désir Black Eye) is a recessive trait that reduces dark body pigmentation while producing solid black eyes. Homozygous NDBE (ndbe/ndbe) geckos display a distinctive "clean" appearance with reduced melanin on the body but dramatically darkened eyes. The trait interacts with melanistic pathways. When combined with tangerine line-bred genetics, NDBE can produce strikingly dark orange to red coloration. The acronym stands for "No Dark Body Extension" in some references, though "Noir Désir Black Eye" is the more commonly used full name. NDBE appears to interact synergistically with tangerine/orange polygenic traits, enhancing color intensity.
How to identify it: NDBE (ndbe/ndbe): Solid black eyes (similar appearance to Eclipse but genetically distinct). Reduced dark body pigmentation. Cleaner, less melanin on the body compared to normal. When combined with tangerine lines, produces intensely colored animals. Heterozygous animals (Ndbe/ndbe) may show darker-than-normal coloration compared to clutch mates but are not visually definitive. NDBE hets can carry the gene invisibly. Best identified through known parentage and test breeding.
NDBE follows a recessive inheritance pattern, carried on the NDBE (Noir Désir Black Eye) allele (locus NDBE).
Because NDBE is recessive, an animal needs two copies of the allele to show the trait visually. An animal with a single copy is called het ndbe (heterozygous). A het animal looks normal but carries the gene, so pairing two het ndbe animals produces, on average, one in four visual ndbe offspring.
