In order to breed Pokémon in Sapphire you either have to breed a female with a compatible male Pokémon or either female or male can breed with a Ditto like a female Treecko could breed with a male Mudkip or Whismur.

Not quite, but almost anything. Legendary pokemon, like Groudon, Kyogre and what-not, no. Most pokemon you can, and the pokemon egg will hatch into the first evolvement of the pokemon that isn't a ditto. But if the pokemon is a legendary pokemon, even if it isn't genderless like Latios or Latias, it can't breed with a ditto. So, generally, in Ruby/Emerald/Saphire, the ones that can't breed with a ditto are:Regirock/Regice/RegisteelLatias/LatiosKyogre/Groudon/RayquazaJirachiDeoxys.Hope I helped! :)
