Reproduction by cloning has been achieved by transfer into enucleated oocytes of nuclei from embryonic cells and more recently from cells of adult animals. The efficiency at which embryos produced by such nuclear transfers will develop into healthy newborns is very low but has allowed to produce some cloned bovines, bovines and mice. Since the first report of sheep cloning from an adult cell in 1997, the potential applications of reproductive cloning in human medicine have been envisaged amidst a flurry of moral debates. Although the technology is still far from being ready for any human use, it has been condemned from the outset. It has also led to irrational fantasies and fears mainly based on the misconception that genetic identity means identical twin personalities. Scientific research is ongoing on refining the cloning technology for applications in the production of genetically homogeneous farm animals with useful nutritional or therapeutic genetic traits. A new area of research is non-reproductive therapeutic cloning for the purpose of producing autologous embryonic cells and tissues for transplantation.

Cloning is a method that is used to produce genetically identical copies of pieces of DNA, cells or organisms. Cloning methods include: molecular cloning, which makes copies of pieces of DNA;...
The goal of animal cloning includes the production of genetically modified animal for human consumption. Therefore, this research endeavoured to study animal cloning’s current …
Animal cloning. Dolly the sheep may have been the world's most famous clone, but she was not the first. Cloning creates a genetically identical copy of an animal or plant. Many animals - including frogs, mice, sheep, and cows - had been …
Animal cloning has been popularized for more than two decades, since the birth of Dolly the Sheep 25 years ago in 1996. There has been an apparent waning of interest in …
Results of animal studies suggest that reproductive cloning of humans would similarly pose a high risk to the health of both fetus or infant and mother and lead to associated psychological …

Animal cloning is an important technique used to produce clones from valuable farm animals, to rescue animals in risk of extinction, and for producing transgenic animals.
