Cloning is a natural mode of asexual reproduction for many organisms, which results in nearly identical copies of cells or organisms. In animals, including humans, identical twins are an example of natural cloning. In the case of sheep, scientists succeeded to produce the "delayed" identical twin. Dolly, of a mature animal by a rather complex and inefficient procedure. However, if this procedure is perfected, it will be useful to clone beloved pets and important laboratory animals. It will be much less suited for making (cloning) "delayed twin" of mature persons because of high costs together with present experimental uncertainties. The only required regulation for human cloning is that somebody must be legally, including financially, responsible for the results of such novel reproductive technique. |
