Hi John,
     Not necessarily so.  Different sets of mutations can converge on
the same morphology independently.  And then there are all the genes
that have nothing to do with the convergent morphology at all.  
      Anyway, the important point is that morphological and molecular
data are both important sources of information, and that they should
eventually become largely congruent (once the wheat is separated from
all the chaff).  The hard part is winnowing out all that chaff (both
morphological and molecular), and studying both types of data will get
you there quicker than just one approach alone.
