Which of the following is an ethical rather than a technical objection to human cloning?
Correct answer: D. A cloned child would be created as a copy of someone else rather than as an individual
- A. The success rate of nuclear transfer is very low
- B. Cloned animals have often shown health problems
- C. The technique needs a large number of donor eggs
- D. A cloned child would be created as a copy of someone else rather than as an individual
Explanation
The first three statements are practical limitations that better technique might eventually overcome, whereas the last concerns human dignity and would remain even if the method became perfectly safe. Distinguishing the two kinds of objection matters, because only the ethical one explains why reproductive cloning of humans is banned outright rather than merely regulated. Therapeutic cloning to grow tissues is judged separately.
