Human Reproductive Cloning

Analysis of Human Reproductive Cloning and Its Unethical Implications Introduction

Human reproductive cloning is a hot button issue , easily invoking images of Huxley ‘s Brave New World or Victor Frankenstein ‘s monster At one time cloning seemed the stuff of fantasy , confined to the realm of literature . However , the notion that humans might conceivably be cloned -produced from a single somatic cell without sexual reproduction- passed further away from science fiction and closer to an authentic scientific possibility on February 23 , 1997 . The Observer announced on that [banner_entry_middle]

day that a Scottish scientist , Ian Wilmut and other researchers at the Roslin Institute were going to reveal the successful cloning of a sheep by a new technique which involved transferring the genetic material of an adult sheep , seemingly obtained a differentiated somatic cell , into an egg from which the nucleus had been taken out . The resulting birth of Dolly the cloned sheep on July 5 , 1996 was different from earlier efforts to create identical offspring since Dolly contained the genetic material of only one parent and was , thus , a delayed ‘ genetic twin of a single adult sheep . Within days of the report on Dolly , President Clinton issued a ban on federal funding to clone human beings in such a way

He also appointed a Bioethical Committee to examine the legal and ethical issues surrounding the subject of a cloned human being ( Human Cloning , pp .1-2 . The Dolly cloned sheep raises many different questions concerning human rights and how we are to respect those rights in light of that it is necessary to define what human reproductive cloning is and is not to determine the ethical implications . Although many in both the scientific and lay communities cheer this potential breakthrough , still more oppose human cloning on moral grounds because it is unethical and the ban on it should remain in place . Definition of Human Reproductive Cloning

Although there are several types of cloning , human reproductive cloning is confined to asexual reproduction , or reproduction without fertilization . A cloned individual (clon from Greek klon , twig slip ) may result from two different processes (1 ) embryo splitting (2 ) cell nuclear replication (CNR ) or cell nuclear transfer (CNT

Embryo splitting purposes are often directed toward therapeutic cloning but can also be used to produce twins . Cloning occurs in nature when an early embryo divides into two separate embryos . These monozygotic twins will be genetically identical . However , the procedure that produced Dolly is CNR . CNR includes two cells , a recipient , which is usually an egg , and a donor cell , such as a skin cell . The nucleus of the donor cell is introduced into the egg with electrical stimulation . These pulses or exposures to chemicals induce the egg to develop until the resulting embryo can be implanted in a viable womb and then developed in the normal way to term , although the failure rate has been high using animal experiments , usually 1 or 2 per hundred . Cloning using this asexual method circumvents the requirements of a… [banner_entry_footer]
