All of the following can help resolve a polytomy in a phylogeny, except more____? a. synapomorphies b. outgroups c. characters d. symplesiomorphies

Solution

d. symplesiomorphies

Polytomy is the node located on a phylogenetic tree, and this will have more than two branches arising from it and it is used to express uncertainty about phylogenetic relationships on a phylogenetic tree.

And synapomorphies outgroups and characters will help us in resolving the polytomy in a phylogeny, but symplesiomorphies will not be useful in doing this.

Both characters and an out-group considered as a good approach to know the evolutionary relationship to the taxon that you are studying.

In addition to this, the synapomorphies can be used to identify monophyletic groups, thus it also helps to resolve polytomy in phylogeny.
