In Sun and Moon, Males, Females, and Genderless Pokmon can pass down their Balls.
However:
- When both Pokmon are the same, they will have 50% chance each to pass down their Pokball.
Ex: Male Ultra Ball Growlithe & Female Great Ball Growlithe = Offspring has 50% chance of having an Ultra Ball, and 50% of having a Great Ball
- When both Pokmon are
NOT the same, only the
FEMALE will pass down the Ball, if the other Pokmon is
MALE.
Ex: Male Ultra Ball Lucario & Female Great Ball Growlithe = Offspring will be Great Ball Growlithe.
UNLESS the other Pokmon is Ditto. If that's the case, a Male paired with a Ditto will pass the Ball.
- Genderless Pokmon can only be bred with Ditto, and Ditto never passes the ball.
Ex: Dream Ball Porygon & Ultra Ball Ditto = Offspring will be Dream Ball Porygon
So Ditto never passes the ball, and the offspring can never result in Ditto.
Also only the Female can determine the offspring's species. Since a Male can't pass down a Pokball to an offspring of another species, you need to be able to naturally
CATCH a Pokmon in a Pok Ball for it to be legal. Since Litten cannot be caught in the wild, only regular Pokball is legal.
