In Generation II only, if the Defense IVs of two Pokémon are the same and the Special IVs are either the same or differ by 8, they cannot produce Eggs. Pokémon in the No Eggs Discovered Egg Group cannot breed in any way whatsoever, and Ditto also cannot breed with another Ditto. As an exception, Ditto is compatible with almost all Pokémon regardless of gender (which is the only way for gender unknown Pokémon to breed). Two Pokémon are compatible if they share at least one Egg Group and are of opposite genders.

Breeding is absent in Generation I, Pokémon Let's Go, Pikachu! and Let's Go, Eevee!, and Pokémon Legends: Arceus. In Generation IX, having a picnic with two or more compatible Pokémon allows for them to breed (regardless of whether the Pokémon are in the player's party or other players' Pokémon visiting via the Union Circle). In Generation VII and Generation VIII, this is instead done by leaving two compatible Pokémon at the Pokémon Nursery. In Generation II through Generation VI, two compatible Pokémon can breed when left at the Pokémon Day Care.
