Ans: Gene cloning could even be a carefully regulated technique that's largely accepted today and used routinely in many labs worldwide. However, both reproductive and biomedical cloning raise important ethical issues, especially as associated with the potential use of those techniques in humans.Reproductive cloning would present the potential of making a person that's genetically just like another one that has previously existed or who still exists. However, some argue that cloning could help sterile couples fulfil their dream of parenthood. Therapeutic cloning, while offering the potential for treating humans affected by disease or injury, would require the destruction of human embryos within the tube. Consequently, opponents argue that using this system to gather embryonic stem cells is wrong, no matter whether such cells are wont to benefit sick or injured people.
