Ethical confusion

PTT

As a bill governing the latest reproductive and cloning technologies makes its way through Britain's Parliament, lawmakers and medical researchers debate what should or shouldn't be considered ethical. At issue are a host of seemingly bizarre creations: human-animal hybrids, embryos with three genetic parents, and possibly even sperm with female DNA. While attempts by conservative members of Parliament to ban the creation of hybrids or "savior siblings"—embryos selected to provide siblings with medical treatment—were voted down, a group of UK scientists pressured lawmakers into removing a section of the bill that would have required embryo researchers to obtain donor consent before using cells from existing tissue banks.
