Dominant ball python gene
Chaos Ball Python: Genetics and Pairing Odds
Chaos is a dominant gene: one copy shows fully, so half the babies from a Chaos bred to a normal are Chaos. Two copies look the same as one, but a homozygous animal passes the gene to every baby.
In Lock and Lay, Chaos 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.

| Pairing | Babies, per egg |
