If the EU picks baby genes

Abstract

Which genes should children never inherit? This is a fundamental question. It arises acutely in medically assisted reproduction, such as in vitro fertilisation (IVF) or artificial insemination. One must frequently choose between different donors, sperm, eggs or embryos. Genetics are one way to choose. But where should the line be drawn? Some see any genetic selection as impermissible. Others argue for selecting out the most severe, purely genetic diseases, such as Huntington’s disease or cystic fibrosis. Some go further: future children should be protected from any genetic diseases or even dispositions to diseases, such as from genes increasing the risk of heart disease. And a few favour selecting for certain non-medical characteristics, such as intelligence or height.
