So how many Pokemon in sinnoh were evolutions to old Pokemon or prevolutions to older Pokemon? I know it's more than in any other gen but I'd like the exact amount.
Evolutions: 22
Roserade Ambipom Mismagius Honchkrow Weavile Magnezone Lickilicky Rhyperior Tangrowth Electivire Magmortar Togekiss Yanmega Leafeon Glaceon Gliscor Mamoswine Porygon-Z Gallade Probopass Dusknoir Froslass
Pre-evolutions: 7
Budew Chingling Bonsly Mime Jr. Happiny Munchlax Mantyke
Generation 4 Pokémon (Pokémon Database)
Hope I helped!
Generation IV introduced the most evolutionary relatives to Pokémon from previous generations, with 29.
Source Hope this helps. 29 in all, including pre-evolutions.
