Question

Organism A shares 50% of its DNA sequences with organism B, while organisms B and C share 90% of their DNA sequences. What can be concluded from this?

Answer 1

"Organism B and C are more closely related to each other than they are to A."

Step-by-step explanation:

I just took the text.

Also, it makes the most sense from the other options. You know that B and C have the most similar DNA, but you can't assume there siblings, you just know that they somehow are related.

Answer 2

organism a is the parent and b and c are siblings
