Question
**the answer for this one is not only E
Why might a phylogeny based only on molecular data show a different pattern of relationships than a phylogeny of the same taxa that is based only on morphological traits? (Select all that apply.)
**the answer for this one is not only E
Why might a phylogeny based only on molecular data show a different pattern of relationships than a phylogeny of the same taxa that is based only on morphological traits? (Select all that apply.)
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) Some highly conserved genetic sequences can result in unrelated species appearing closely related in a molecular phylogeny, and not reflect the same pattern as the morphologic phylogeny. D) 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. E) Gene sequence changes may not result in morphological changes.Explanation / Answer
The correct reasons are:
C) Some highly conserved genetic sequences can result in unrelated species appearing closely related in a molecular phylogeny, and not reflect the same pattern as the morphologic phylogeny.
E) Gene sequence changes may not result in morphological changes.
