Answer 1

I don't think it is a sucker but I don't see the graft. You should be able to tell when it leafs out. If it has leaves different from the other stems, it is probably a root stalk. But be careful though, because mulberries can have different shaped leaves on one tree. The article below shows the varying leaf shapes.
