Dolly was the first clone produced from a cell taken from an adult mammal. The production of Dolly showed that genes in the nucleus of such a mature differentiated somatic cell are still capable of reverting to an embryonic totipotent state, creating a cell that can then go on to develop into any part of an animal.
Was Dolly the sheep ethical?
Dolly the sheep’s scientific and ethical legacy. The team of scientists responsible for the birth of Dolly the sheep believed their achievement would help transform the fight against disease.

Why is human cloning unethical?
Because the risks associated with reproductive cloning in humans introduce a very high likelihood of loss of life, the process is considered unethical. There are other philosophical issues that also have been raised concerning the nature of reproduction and human identity that reproductive cloning might violate.
Are Dolly’s clones still alive?
Dolly the sheep died young, but her cloned sisters are still alive and kicking.
What ethical issues are involved in cloning?
Ethical issues specific to human cloning include: the safety and efficacy of the procedure, cloning for destructive embryonic stem cell research, the effects of reproductive cloning on the child/parent relationship, and the commodification of human life as a research product.
