Accuracy and limits

Breeding combinations come straight from the game data and are updated when the data is.
Passive and IV inheritance odds follow PalCalc's community-tested model. They are estimates, not official numbers.
Mutations arrived with 1.0 and have no published odds, so PalBreeder lists only what is confirmed. See Mutations.
