Question

Animal A and Animal B each have 95% of their DNA in common. Animal A and Animal C each have 50% of their DNA in common. What does this suggest about the relationship of these animals? A. B is probably much more closely related to C than to A. B. C is probably much more closely related to B than to A. C. A is probably much more closely related to B than to C.

Answer 1

C) A is probably much more closely related to B than to C.
Because A/B have 95% DNA in common, but A/C only have 50% in common.

Answer 2

Answer: The correct answer is-

C. A is probably much more closely related to B than to C.

As per the information given in the question, Animal A and B have 95% of their DNA in common whereas Animal A and C have 50% of their DNA in common. This indicates that DNA sequence of Animals A and B are more similar as compared to the DNA sequence of Animals A and C.

DNA is the genetic material of living organisms that is transferred from one generation to the next. A change in the sequence of DNA takes place when organisms evolve.

Two organisms are said to be related to each other if they share more genetic relatedness ( that is similarity in their DNA sequence).

Thus, option C) is the right answer.
