The red dots on the tree represent the known shared derived traits among the species. If species 1,2,3 and 4 were grouped into a single genus (no other species), this genus would be considered paraphyletic . (monophyletic; paraphyletic; polyphyletic) If species 4,5,6 and 7 were grouped into a single genus (no other species), this genus would be considered [ Select ] . (monophyletic; paraphyletic; polyphyletic) If species 5,6,10,11, and 13 were grouped into a single genus (no other species), this genus would be considered polyphyletic . (monophyletic; paraphyletic; polyphyletic) How many synapomorphies are shared between 9 and 12? [ Select ] How many synapomorphies are shared between 1 and 2? [ Select ]

Step 1
- A paraphyletic group includes a common ancestor and some, but not all, of its descendants. - In the cladogram, species 1, 2, 3, and 4 share a common ancestor, but not all descendants are included (species 5 and beyond are excluded). - Therefore, this group is Show more…

Use this phylogenetic tree to answer the questions below: 1. Interpret the phylogenetic tree shown below to answer the following questions: [½ pt each = 3 pts total] a. Highlight the node (branch point) that represents the most recent common ancestor of A and B. b. Which species is the outgroup? Highlight the one: A B C D E F G c. Which species have trait 1? Highlight all who do: A B C D E F G d. Which species have trait 2? Highlight all who do: A B C D E F G e. Which species is/are most closely related to E? f. Which species is/are most closely related to F?

Construct a cladogram that meets the following criteria: (25 marks) 1. Consists of five taxa – A, B, C, D, E 2. Taxon A is the sister group to B 3. Taxon C is the sister group to D 4. Taxon E is the sister group to CD 5. Taxon AB is the sister group to CDE 6. Taxon AB is the most ancestral (primitive) 7. Label the following: root, node, clade, speciation event 8. Draw a circle around taxa to create a monophyletic group 9. Draw a circle around taxa to create a polyphyletic group, a paraphyletic group
