After Dolly came other sheep, cows and even rhesus monkeys cloned using similar techniques, but with slight variations. These cloned animals came from Roslin and many universities from across America. They even produced clones, which had genes that would produce certain proteins. The goals and purposes for researching cloning range from making copies of those that have deceased to better engineering the offspring in humans and animals. Cloning could also directly offer a means of curing diseases or a technique that could extend means to acquiring new data for embryology and development of organisms as a whole.
Cloning also provides better research capabilities for finding cures to many diseases.
There are also possibilities that nuclear transfer could provide benefits to those who would like children. For instance, couples who are infertile, or have genetic disorders, could use cloning to produce a child. Equally important, women who are single could have a child using cloning instead of in-vitro fertilization. Nuclear transfer could also provide children who need organ transplants to have a clone born to donate organs. Cloning could also provide a copy of a child for a couple whose child had died.
