Noir Desir Black Eye
Gene
Noir Desir Black Eye, often shortened to NDBE, is a recessive leopard gecko eye trait: hatchlings have fully black eyes, and the black can spread out or fade with age. A gecko needs two copies to show it, and test crosses show it is a different gene from Eclipse. Eye deformities are reported in some NDBE geckos, and one reference reports infertility in many visual females.
