Multicast Many-to-one SPT switchover

In the case where multiple sources are present for the same multicast group in a PIM-SM environment:

1. Will the PIM DR choose one or multiple sources to send the PIM join during the SPT switch-over process ?

2. If one source is chosen, how does the election take place? If several sources are chosen, does this mean the receiver will receive duplicate packets?
