ethics & pre-implantation genetic diagnosis

A question in the 2007 Scholarship exam asked you to discuss the impact of various forms of genetic testing on the human gene pool. One of those techniques was pre-implantation genetic diagnosis, or PIGD: testing very early embryos for the genetic markers linked to a variety of conditions (or, where known, for the genes themselves).

Now I’ve come across a thought-provoking article dealing with some of the ethical issues associated with PIGD. Whether or not you agree with the points being made, the article’s sure to stimulate ideas & discussion.
