This question already has an answer here:

If someone was to take Tonks's hair, as she is a Metamorphmagus, does that mean that they can change their appearance just like her, as Polyjuice Potion copies all of the attributes of the person you are transforming into, or would they only be able to turn into Tonks?

    @Valorum I don't agree that this is a duplicate. The other question asks what appearance would be used. It doesn't ask whether the actual ability to change appearance is also granted to the person who took Polyjuice Potion. – Anthony Grist Jan 16 at 14:08

    Whilst the target is focused on what form would the person take the actual question asked is "What would happen?" which encompasses "Would you gain their abilities?" – TheLethalCarrot Jan 16 at 14:16

    @TheLethalCarrot A question is more than just its title. "What would happen?" is very broad (arguably even too broad), but the OP of that other question appears to have clarified that by "What would happen?" they actually mean "What would happen to the taker's appearance?" We would have to edit that question to expand its scope, which while not invalidating the existing answers would make them only partial - rather than full - ones, and I'm not convinced that's any better than edits that just outright invalidate answers. – Anthony Grist Jan 16 at 14:24
