Recessive ball python gene

Paint Ball Python: Genetics and Pairing Odds

Paint is a recessive gene. A ball python needs two copies to look Paint; with one copy it looks normal and is called het Paint. Pair two hets and about a quarter of the babies are visual Paint, 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 Paint projects start.
