What are the potential medical benefits of animal cloning?

Genetic modification can be used to disguise an animal’s cells and organs and thereby reduce or even eliminate rejection of the graft. Thousands of people die every year because of the unavailability of human organs for transplantation. Genetically modified animal organs could begin to fill this need.

Does the US support reproductive cloning?

Any ban on human cloning should explicitly state that it does not prohibit the use of nuclear transfer or other cloning techniques to produce molecules, organs, plants, tissues, cells other than human embryos, or animals other than humans. The United States does not support a ban limited to “reproductive” cloning.

Was Dolly the sheep infertile?

Not the usual sperm + egg She lived to six and a half years, when she was eventually put down after a contagious disease spread through her flock, infecting cloned and normally reproduced sheep alike. Her life wasn’t unusual; it’s her origin that made her unique.

How many attempts did it take to clone Dolly?

To give you an idea how hard this was, Dolly (initially identified as 6LL3) was the only lamb born alive from 277 attempts! It was reported that 29 embryos were successfully created, and subsequently implanted into 13 surrogate mothers, but Dolly was the only pregnancy that went to full term.
