You may already know that if you catch two Pidgeys, they may have a different skillset.
I've also seen that evolving them from different skillsets will also create Pidgeottos with different skillsets.
Are those skills chosen randomly or do they follow a specific pattern? (Like Pidgey pattern 1 will always evolve into Pidgeotto pattern 1.)
If they are specific, is there a website to check for them?
