http://humansfuture.org/genetic_engi...babies.php.htmMost of us have seen the term 'designer baby' used by the media. The term conjures up images of couples sitting down with a catalogue and carefully selecting each feature, characteristic and trait one by one; sex, eye and hair colour, height, weight, talents, definitely not the father's nose. The whole idea is both exciting and frightening and most certainly rife with ethical issues. The term 'designer baby' is a misnomer, unless your crediting nature as the architect. Within the constraints of current scientific capabilities a more real term might be 'Selected Baby'. The scientific reality is far removed from the media fervour. You can select an embryo with the right chromosomes to produce the child of your chosen sex or have the embryo screened for a potential hereditary genetic disorders, or choose an embryo that is a genetic match for a sibling who already has a genetic disorder, but anything else is pure hypothesis.
Future Science
Above is outlined what is currently scientifically possible and as we can see it is possible to identify certain genetic anomalies that indicate the presence of a predefined genetic disorder or disease and to identify a male or female embryo, but this page is suppose to be about 'designer babies'. Within the realms of current scientific capabilities creating a truly designed baby is simply not possible, some knowledge exists as theories and some experimentation with animals has taken place, but so far to the best of our knowledge no-one has dared to attempt to genetically design a human.
So what needs to be discovered to enable the parents of the future to sit down with their catalogue and tick the hair, eyes, nose, talents boxes?
Scientist will need to do a lot more work on identifying and isolating the specific genes that control the growth and development of each individual feature, trait, characteristic or talent. Then they will need to work out how to alter the DNA so that the child matches the tick boxes. Now, we know that the formation of the human is a highly complex process of interaction and interweaving and not simply a case of take this gene, change it and hey presto the baby that was going to have green eyes will now have brown eyes. There is a great deal of uncertainty and fear about what might happen once we start to 'mess around' with our offspring's DNA, but it probably will happen eventually and parents are likely to be able to sit down and start ticking those boxes.
will it be possible to design a master race without hereditary diseases, stronger, more intelligent etc.?
