The Morph Library
Look up each morph and its illustrated variations.
The Morph Library is a public reference for the looks Gecktopia can draw. Its entries show the morph on a gecko, explain where it appears, and show how it changes with other genes. Library art is an example of a look, not a prediction for a particular egg.
Open the Morph Library and choose a morph from the contents. Read its examples before choosing a breeding goal, then use Pairing to see what your own parents could produce. The Library explains the look; the pairing preview gives the odds for your selected geckos. Start with the Axanthic sheet to compare an illustrated look with the inheritance odds.
