Recessive ball python gene

Cryptic Ball Python: Genetics and Pairing Odds

Cryptic is a recessive gene. A ball python needs two copies to look Cryptic; with one copy it looks normal and is called het Cryptic. Pair two hets and about a quarter of the babies are visual Cryptic, while the normal-looking siblings are each 66% likely to be het. Breed a visual to a normal and every baby is het, which is how most Cryptic projects start.
