The moral argument for three-person babies
From our UK edition
If all goes according to plan, the first baby with the DNA of three people will be British, and could be born next year. Mitochondrial transfer could end years of misery for some couples and prevent appalling conditions being passed on to the next generation. Some scientists have raised concerns that it’s such uncharted territory that the babies could be born with disabilities or genetic defects, but the majority are happy that the research has been through necessary reviews. Melanie McDonagh and Isabel Hardman have drawn attention to the breakneck speed with which MPs voted to legalise the procedure. Parliament should act as a national conscience, and we don’t want them essentially outsourcing complex decisions to experts.
