Three parent babies?

 

A recent lecture by Karen Bridwell mentioned an article that left me intrigued. In the lecture she mentioned that the headline was due to governmental bodies stopping the use of a new IVF technique. The controversial title seems aimed to shock people into reading the article.

 

In this new IVF, small amounts of a second woman’s genome replaces damaged genes from the mother, meaning babies would have DNA from three people; two women and one man. An article by the telegraph points out that this DNA does not just affect the first generation, but every generation after.

 

Although the technique developers insist that the DNA that is swapped has no bearing on the child’s physical or physiological development, from a scientific standpoint I see it as having ethical issues. How long until this technique will be used to make ‘designer babies’, or does creating a healthy child in a lab constitute anyway?
