Why might a phylogeny based only on molecular data show a different pattern of relationships than a phylogeny of the same taxa based only on morphological traits?
a)gene sequences always provide more data than morphological traits.
b)morphological analyses always provide more data, because each morphological trait is the result of the expression of many genes.
c)the molecular data may be based on the analysis of introns, which aren't expressed and don't contribute to the evolutionary history of a group of taxa.
d)some highly conserved genetic sequences can result in unrelated species appearing closely related in a molecular phylogeny, and do not reflect the same pattern as the morphologic phylogeny.
