W:Welcome to the Genetic World. Dr Smith is going to give his opinion about the cloning of human beings. Dr smith, is it possible to copy human beings at present?
M:Well, the cloning of human beings is a very inefficient procedure. Even if the technique were perfected, we must ask ourselves what practical value human cloning might have. Why do we copy people? Firstly, couples unable to have children might choose to have a copy of one of them. The parents would be more likely to place higher expectation on the cloned child than average parents. Cloning is also suggested as a means of bringing back a relative, usually a child, killed tragically. But it must be first recognized that the copy would be a new child and not the lost child.Thirdly, copying is suggested as a means by which parents can have the child of their dreams. Couples might choose to have a copy of a film star, baseball player or scientist, depending on their interest. But what if the child does not live up to their hopes. In my opinion, each child should be wanted for itself, as an individual. I suggest that there is a greater need to consider the interests of the child. And we should reject these proposed uses of cloning.
