Debate on Designer Babies

Genetically modified babies will soon be walking among us, and thus there is a debate in the scientist community. Read further about designer babies.

"Alpha children wear gray. They work much harder than we do, because they're so frightfully clever. I'm awfully glad I'm a Beta, because I don't work so hard. And then we are much better than the Gammas and Deltas. Gammas are stupid. They all wear green, and Delta children wear khaki. ...
... Oh no, I don't want to play with Delta children. And Epsilons are still worse. They're too stupid to be able to read or write. Besides they wear black, which is a beastly color. I'm so glad I'm a Beta."
When Aldous Huxley coined this quote in 1932 in his novel 'Brave New World', he had no idea how intense the debate on designer babies could become a mere century later.
His book was a satirical look into a Utopian society, where people were segregated on the basis of genetic modifications that they were subjected to as embryos. The end result was a seriously disillusioned world where these modifications brought on a revival of the Dark Ages.
The debate, today, is something that the public eye has been shielded from, and for good measure. Companies like Google and Amazon have banned advertisements of gene modifications in many countries, as it is an issue that really splits opinion.
It is in the confines of scientific labs and multinational companies' conference halls that this debate is slowly rising and threatening to boil over.

What are Designer Babies?

Picture a world where parents of a yet unborn child can modify his/her genes, and determine his/her physical appearance, cleverness, and resistance to disease. It sounds like stuff that science fiction movies are made of, but we are fast approaching a day when this method will be guaranteed to work. What happens to the world after that, remains to be seen.
According to the Oxford English Dictionary, a designer baby is 'a baby whose genetic makeup has been artificially selected by genetic engineering combined with IVF (In Vitro Fertilization) to ensure the presence or absence of particular genes or characteristics.'
The process involves fertilizing the egg by the sperm in a test tube outside the mothers womb, and altering the genes. Admittedly, the purpose is noble (to eradicate genetic disorders and diseases), but where will the human race really draw the line?
Who is to stop affluent families (for this is an expensive procedure) from using these methods to change their child's eye color, or to make him a professional football player, or to make her slender and gorgeous? The debate is more about how we are learning to sidestep nature, and how this could crumble society as we know it today.
The process of selecting the traits and characteristics of children is also known as Pre-implementation Genetic Diagnosis (PGD), and here, the embryo is checked for genetic deficiencies before it is returned to the mothers womb. Suitable alterations can be made along the way, and the repercussions that this will have is open for debate.

Ethical Concerns

The ethical considerations come into play because of the effects this procedure will have. Families that can afford these alterations will be few, and this will only increase the disparity between the various social classes. This will ultimately result in a segregation between the superior 'modified' humans, and the pure, but inferior ones.
Sooner or later, this situation will turn ugly. Moreover, the diversity of the gene pool and human genetics will be affected, and this may even lead to a major percentage of the human race being wiped out completely by some major disease. All this is without even taking into consideration the effect this procedure will have on the child.
People involved in these debates sometimes forget to think about the effects these alterations will have on the children. After all, if you are tweaking one gene here, then another gene somewhere else must be shifting to balance the event.
This could ultimately lead to a situation where each child is programmed to do certain tasks, and is unable to do anything else, much in the way Aldous Huxley envisaged. Moreover, the freedom of the child to choose a profession of his choice in the future, will also be severely diminished. The ethical repercussions of this are not very pleasant.
The human race must stop trying to play God by messing with genetics and embryo alterations, and this is exactly what the debates are all about. Though it is too late to eradicate these procedures entirely, we can still do our best to control the situation.
The purpose may be noble (to eradicate genetic diseases), but in the wrong hands, this knowledge could be devastating. And human beings do have a tendency to allow such knowledge to ultimately fall into the wrong hands.
