Designer Babies

By Theresa Phillips, About.com

Developments in genetic research and in vitro techniques for reproduction have led some to theorize that, in the near future, wanna-be parents will be able to create designer babies with the specific traits they desire: Essentially, GM Humans.

How ethical is it, to create a genetically modified child, with custom-selected traits? Submit your vote on page 2.

Current Status
While the technology isn't yet available, the fact that people are talking about it means there are laboratories willing to make the effort to make it possible, no matter what the ethical costs. At this point in time, we only just beginning to understand how sex is determine in an embryo, or the epigenetic controls that cause one gene to be preferentially expressed over another during blastocyst development. This kind of knowledge could then concievably be applied to test tube babies, but we are a long way off from that yet.
Background

As we learn more about stem cells and differentiation of pluripotent cells and epigenetics, the concept of controlling cell differentiation becomes more real. If we can control tissue formation and the size and shape of organs and expression of genes controlling human traits, we can make designer babies.

The conclusion of the human genome project has also contributed to this fantasy of GM children, since scientists have now sequenced each and every gene in the human cell and we are also well on our way to determining the function of each.
