A scientist is attempting to build a cladogram that shows the evolutionary closeness of three organisms in relation to humans. After doing DNA analysis, they determine that the organisms share the following percentages of DNA:

Question

Organism A and humans share 85% of their DNA.

Organism B and humans share 80% of their DNA.

Organism C and humans share 90% of their DNA.

Based on this information, which order should they go on the cladogram (from least related to most related)?

(1 point)
Responses

B, A, C, humans
B, A, C, humans

C, A, B, humans
C, A, B, humans

C, B, A, humans
C, B, A, humans

A, B, C, humans

Answer 1

To determine the correct order for the cladogram based on the percentage of DNA shared with humans, we should list the organisms from least related to most related based on their shared DNA percentages:

1. Organism B shares 80% of DNA with humans (least related).
2. Organism A shares 85% of DNA with humans.
3. Organism C shares 90% of DNA with humans (most related).

Therefore, the correct order from least related to most related is:

B, A, C, humans.

So, the correct response is:

B, A, C, humans.
