Crested Gecko Genetics tools: what they help with

These calculators predict the likely colors, patterns or morphs from a crested gecko pairing, using the known inheritance of each trait. Understanding genetics helps breeders avoid pairings linked to health problems and set realistic expectations about offspring.

What to know about genetics and morphs for crested geckos

Crested geckos typically live 15 to 20 years. Crested geckos are arboreal and need a tall planted enclosure rather than a wide one, kept at room temperature between 22-26C. They thrive on prepared powdered diets and cannot tolerate heat above 28C.
