Step 1

A phylogenetic tree is a tree diagram that picturizes the evolutionary relationship between the various species. The branching pattern in the phylogenetic tree represents that species of a common group or the other group are ultimately evolved from the same ancestor. For example, in the given phylogenetic tree the common ancestor of all the given species is blue-eyed, white antenna, and smooth leg cockroaches.  

Step 2
  1. A) According to the given phylogenetic tree, species D have a white antenna, red eyes, and smooth legs.

Species C have a red antenna, blue eyes, and smooth legs.

Species G has a yellow antenna, green eyes, and hairy legs.

So, from the above observation, it is clear that species C and D are common to each other in terms of smooth legs.

Hence, species D is closely related to species C.              

  1. B) Monophyletic taxon involves a group of species that have the same phenotype which is inherited from the same ancestor.

A polyphyletic taxon is a group of species that have the common trait but have different ancestors.

A paraphyletic taxon is a group of spec...
