Yes, or mutations occurred which affected the stability of the (+)-sense strand.
Is there any evidence that amongst the (+)-strand virions there are some (-)-strand
containing particles also ? At a pinch, with todays PCR technology we should be
able to answer that question if it hasn't already been done.
