Modern technology is allowing parents and doctors to screen babies for genetic disorders, diseases etc. This can happen either by testing the sperm / egg cells before fertilization (making test tube babies, essentially), or through gene therapy - which involves testing on an embryo.
The general fear / controversy on this subject is the fact that some people think this will stop being just about curing genetic defects - and move onto people choosing hair colour, eye colour etc.
What's your opinion?
