Executive Summary The technology of cloning has been existing for more than one century. Since the very first cloned sheep Dolly was created in February 1997, which stands out as one of the notable landmarks in the progress of cloning technique, the application provides a new tool for agriculture, medicine and biological basic mechanism research. With the rapid development of cloning technique, it has become a double-edged sword that has both application values and disadvantages to the human society. Introduction A bacterium can reproduce by dividing itself into two within 20 minutes; a vine branch cut into ten segments can plant ten grapevine; a strawberry plant can produce hundreds of strains within a year by crawling along its stolon. In nature, some plants and single-celled organisms produce genetically identical posterity through a process called asexual reproduction. In asexual reproduction, a new individual is generated from a copy of a single cell from the parent organism, which can also be called “clone” [1]. At early stage, Theodore Puck stated that “A clone is a population of cells, all of whose members are descendants from the same single organism” [2]. While with the development of time, the term “clone” has been defined more broadly. It can be described as the process used to create an exact copy of a mammal by using the complete genetic material of a regular body cell, or organisms that are exact genetic copies. Cloning technique has
