Length: 300 words Most parents intend the best for their children. But do parents have a duty to avoid harming their children by passing on genetic or other diseases to them? What are the ethical implications of prenatal testing? Is it an ethical requirement or ethically problematic? Asch discusses how the attitude of trying to give a child the best chances in having a good life can be also seen as discriminatory against a group, namely, those with disabilities. Is that right? How do the ethical questions change when the method of prenatal testing is no longer amniocentesis, but PGD? We’ll especially consider that question with respect to sibling donors.
