Recessive ball python gene
Rainbow Ball Python: Genetics and Pairing Odds
Rainbow is a recessive gene. A ball python needs two copies to look Rainbow; with one copy it looks normal and is called het Rainbow. Pair two hets and about a quarter of the babies are visual Rainbow, 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 Rainbow projects start.
In Lock and Lay, Rainbow can't be bought at the start. It turns up only as a spontaneous mutation, from a lucky egg, and the first breeder to hatch one gets their name on the discovery board.
