Only generation-I Pokemon are available, however it seems that the types which did not exist in Gen-I do exist in Pokemon Go (e.g. Dark type moves).
So I'm wondering which type chart the game is using for move effectiveness.
According to Bulbapedia, in Gen I Bug attacks were super-effective against Poison, but in Gen II-V Bug attacks are not very effective against Poison. What is it in Pokemon Go?
Similarly, in Gen II-V Ghost attacks are not very effective against Steel, but in Gen VI Ghost attacks are normal effective against Steel. Does anyone have a Magnemite, is it Steel type? Does it resist Ghost?
Does STAB exist in this game?
