In the Reptile hobby, we classify mutant genes based on how they interact to morph the animal's appearance from its wild form. An animal may carry zero, one, or two copies of a mutant gene. If it only carries one gene (i.e., half the pair), we refer to it as the heterozygous form since it has the mutant gene paired with a the normal/wild type gene. When the pair is present, the animal is said to be homozygous for that gene.

MorphMarket has one of the most comprehensive databases of reptile genetics in the world, and we're constantly improving and expanding it. Our genetics engine is at the heart of our site and powers the search, ad importing, genetic calculators and more.
We've finally broken up the Ball Python Axanthic trait into its multiple lines. You can now search for Axanthics specifically by VPI, Snake Keeper, Jolliff or Marcus Jayne variety. This is an important distinction since these lines are incompatible.
