Evo i nekoliko nau?nih razloga u korist tzv selektivnog kloniranja ljudi:
"Many hopes have been put upon human cloning. Therapeutic cloning could provide needed organ transplants. A cure for cancer by a better understanding of the cell-differentiation process, as well as better treatments for heart attacks and improved cosmetic surgery, are being cited as being possible with the new technology. Dr. Richard Seed thinks that human cloning will help us understand, and eventually reverse, the human aging process.
Antinori and Zavos hope to create a fertility treatment that allows parents who are both infertile to have children with at least some of their DNA in their offspring. Some families have high hopes for reproductive cloning. How to Build a Human, a documentary by BBC and Discovery Channel, illustrated the prospects by showing an American family that wants to make a clone of their third child, who, although genetically healthy, had serious mental and physical deficiencies due to complications at birth and is expected to die soon. Other people hope to clone their already deceased children. Jonathan Colvin, in an interview on the CBC, expressed his desire to clone himself while repairing his genetic defect (cystic fibrosis), thereby creating a version of himself free of the fatal disease."
