Therapeutic cloning



Cloned organs would eradicate problems with transplant rejection

Supporters of cloning say it could offer numerous benefits in the future.

Therapeutic cloning might create perfect-match organs for transplant or cells to fight degenerative human conditions like Alzheimer's disease.

Reproductive cloning could give infertile couples the chance of a baby, or preserve an endangered species.

Cloning could be an ideal way to mass-produce elite farm animals with particular valuable qualities, such as dairy cows with a high milk yield.
