Describe the background and basic issue of designer babies

The first designer baby was created in the U. S. in 2000. Doctors used screening techniques to test the embryos of Lisa and Jack Nash. They chose the embryos that would be an exact cell match to their daughter Molly. Molly suffers from a genetic disorder called Fanconi Anemia which causes bone marrow deficiency. The embryo selected did not carry the disease and was a perfect tissue match. As a result, Adam Nash was born in August after Mrs. Nash underwent four IVF cycles. Stem cells were collected from his umbilical cord to be donated and used to replace Molly's bone marrow. (Baby created to save older sister) Since the creation of Adam, many more couples have created their own designer baby to save their sick child or prevent their offspring from inheriting a certain genetic disease.
