Page 6 BIOL 413, Exam 1, 14 September 2017 Name (8 points) Based on the following phylogenetic tree of 7 species (A-G), a large number of different classifications can be proposed. For the classifications listed below the tree, (a) indicate the kind of group that is represented by each genus (monophyletic, paraphyletic, or polyphyletic) and (b) briefly discuss why you chose to apply the different terms, being sure that you make it clear that you can differentiate among monophyletic, paraphyletic, and polyphyletic. Classification Classification II Genus 1 Classification 1 Genus I Genus 1 Species E Species F Species G Species C Species D Species D Species F Genus 2 Genus 2 Genus 2 Species A Species B Species C Species D Species E Species F Species G Species A Species B Species C Genus 3 Genus 3 Species A Species B Species E Species G Classification I1 GenusI Classification I: Classification III: Genus 1- Genus 1- Genus 2- Genus 2 Genus 2- Genus 3 Genus 3-Explanation / Answer
Classification 1:
Genus 1 is monophyletic as this group involve ancestor and it's common recent descendents.

Classification 3:
Genus 1, genus 2, genus 3 all include paraphyletic group because it include some descendent of along with common ancestor.
