Cloned dolly was identical to the:

Correct answer: D. Both b and c

  • A. Parents who gestated and gave birth to Dolly
  • B. Parents, who donated egg cell
  • C. Parent, who donated somatic cell
  • D. Both b and c

Explanation

The correct answer is Option D: Both b and c. Dolly, the cloned sheep, was identical to the sheep whose somatic cell was used for cloning (Parent who donated somatic cell) and the sheep whose egg cell was used for cytoplasmic and mitochondrial DNA (Parents, who donated egg cell). This combination of genetic material resulted in Dolly being a clone of the original sheep.Options A and C are incorrect because Dolly's genetic material did not come from the parents who gestated or gave birth to her, or from the parent who donated the egg cell.
