A few days ago I wrote about the possibility that we are creeping towards some form of brave new world as various genetic testing options become more feasible. I’ve an update for an earlier story that follows along with that post.
I’ve written several times about three-parent IVF. The idea is that mitochondrial DNA from one woman is used in conjunction with the nuclear DNA of a second woman as well as sperm from a man. This could be useful where the nuclear DNA provider carries flawed mitochondrial DNA, which could cause a variety of diseases. Anyway, they’ve been studying the process in Britain, focussing on the question of whether it is ethical.
The answer, offered by Nuffield Council on Bioethics, is that it is. If you prefer press coverage you can find that as well.
I am not sure I have much to add to what I’ve said before (see link above), except that you can see this, too, as a small step towards genetically engineering new human beings. Indeed, the whole point of this procedure would be to create a genetically unproblematic embryo–and that could be seen as eugenics. Here’s a look at one set of arguments against the procedure and you can see the eugenics point being raised down towards the bottom of the essay.
