#15 Jeff McMahan: On the ethics of choosing our children's genes

Bio(un)ethical

In this episode, we speak with Dr. Jeff McMahan, Emeritus Sekyra and White’s Professor of Moral Philosophy at Oxford University, about whether germline gene editing is ever morally preferable to embryo selection and whether and when we should control the genetic outcomes of our children.
