Is breeding with Ditto bad?
As previously mentioned, Ditto breeding with gendered Pokémon results in less biodiversity. Most often, it’s comparable to Pokémon cloning, with very few new or unique features being added, such as Hidden Abilities or new moves. Ditto can only do this, of course, because it can transform into any Pokémon.
What happens if you breed a Genned Pokémon?
Pokémon that are hatched from Eggs can have access to stronger attacks, known as egg moves.
