Which of the following is an accurate statement of the relationships within this cladogram? The image depicts a cladogram with numbered and lettered branches. The image includes clades one, three, and seven on one fork of the tree, and clades two and four on the other. From clade one moving up the tree, the first fork is clade two which ends in organism group D. From clade two, clade five diverges ending in organism group C. Clade one continues up the tree, ending in organism group A. Toward the end of clade one, clade four diverges, ending in organism group B. On the remaining branch of the tree, moving upward from clade one, clade three diverges, ending in organism group E. From clade three, clade six diverges ending in organism group F. Clade seven diverges from the main branch, ending in organism group G, and the main branch ends in organism group H. Clades A and C are more closely related than clades A and D. Clade 1 is ancestral to all the other clades. Clades 3 and 7 are more directly related than clades 3 and 6. Clades 4 and 5 are ancestral to clades 1 and 2.

A cladogram is a tree-like graphic representation that expresses the relationship among several taxa. The correct option is B. Clade 1 is ancestral to all the other clades.

What is a cladogram?

A Cladogram is a graph drown as a tree, which is based on cladistic analysis.

It represents the common ancestral relationships and the emergence of different characters among the involved groups.

The tree-type graph is a ramified diagram that represents the relationship between the involved taxa.

It follows the maximum parsimony criterium, which explains the character state from the point of view of the fewest possible changes through history.

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

The derivated character is any trait that emerges at some point of history in a group and is inherited by all the descendants. All the subsequent groups in the cladogram carry the trait.

Cladogram structure

The cladogram is composed of

  • Lineages → The taxonomic groups of interest. These are placed in the extremes of the branches.  

  • Nodes → These are the ramification points, which are also known as divergence points. They represent the location of the most recent common ancestor.  

  • Root → This is the older common ancestor that all lineages share. The first one in the tree.  

According to this framework about cladograms and the given information, the correct option is B. Clade 1 is ancestral to all the other clades.
