The cladogram shown below describes the evolutionary relationship among several species, labeled A to F. The five dots represent derived characters. A cladogram includes a line with 5 dots. From bottom to top, the dots are labeled Trait 1 to Trait 5. Branches from the line lead to tips labeled A to F. Labels C and D are at the ends of very short branches off a longer branch.

The cladogram supports which of these predictions about the genomes of the six species?

A. The genome of species E is equally similar to the genomes of species D and F.

B. The genome of species E is more similar to the genome of species F than to any of the other species.

C. The genomes of species C and D are nearly identical because neither species has a derived character.

D. The genomes of the six species share few, if any, DNA sequences.

(You will find the cladogram in the attaches files)

C. The genomes of species C and D are nearly identical because neither species has a derived character.  

Explanation:

A Cladogram is a tree-type graph based on cladistic analysis. It represents the common ancestral relationships among the involved groups.

So the cladogram represents the relationship between groups according to a derived character.

The derivated character is any trait that a group passes to the descendants. Through evolution, the characters change, and new changes are added. When referring to a derivate character, we mean that all the subsequent species in the cladogram carry the trait.

A cladogram provides an image of how new species keep characters that were inherited from older species.  

So, in the exposed example, the five dots represent derived characters, representing traits 1 to 5. Branches A to F, represent groups. (See the cladogram in the attached files). Group A inherited trait 1, group B probably still carries trait 1, but also trait 2. Groups C and D equally inherited trait 3. Group E inherited character 4, and finally, group F inherited character 5.

Groups C and D inherited trait 3 and probably also still have traits 1 and 2. So they are very similar to each other. At a certain point, they diverged, probably due to a new mutation that was not passed to the rest of the group.  

C. The genomes of species C and D are nearly identical because neither species has a derived character. Correct.

emerald ash borer

the emerald ash borer is a green buprestid or jewel beetle native to north-eastern asia that feeds on ash species. females lay eggs in bark crevices on ash trees, and larvae feed underneath the bark of ash trees to emerge as adults in one to two years. hope this !
