Discuss the ethical issues both for and against associated with PGD selection of savior babies. ...

Couples have used IVF and PGD to have babies who were tissue-matched to siblings with leukemia and other diseases. In these cases, the embryos were not screened for genetic disorders only for alleles that would allow the children produced from the embryos to serve as transplant donors for their siblings. These cases have reignited the debate on whether it is ethical to select for genotypes that have nothing to do with a genetic disorder and whether screening to benefit someone else is acceptable. Advocates of embryo screening to match transplant donors and recipients say that there are no associated ethical issues, but critics wonder if embryo screening for transplant compatibility will eventually lead to screening for the sex of the embryo or designer baby traits. A survey by the Genetics and Public Policy Center at Johns Hopkins University shows that 61 of Americans surveyed approved of using PGD to select an embryo for the benefit of a sibling, but it also revealed that 80 of those surveyed were concerned that reproductive genetic technologies could get out of control.
