You will have to ask both authorities.
Some countries give nationality by birthplace (e.g. USA), some by parentage (e.g. Sweden), some by both. It really depends.
BTW having the actual passport does not change status. That is, you could be a citizen without the passport. It is just a proof of citizenship for travel purposes.
