What is a designer baby?: "dvanced reproductive techniques involve using InVitro Fertilisation or IVF to fertilise eggs with sperm in 'test-tubes' outside the mother's body in a laboratory. These techniques allow doctors and parents to reduce the chance that a child will be born with a genetic disorder. At the moment it is only legally possible to carry out two types of advanced reproductive technologies on humans. The first involves choosing the type of sperm that will fertilise an egg: this is used to determine the sex and the genes of the baby. The second technique screens embryos for a genetic disease: only selected embryos are implanted back into the mother's womb. This is called Pre-implantation Genetic Diagnosis (PGD)."
This is a great link! It's better than CATS.
