London - A new row over "designer babies" erupted yesterday after medics said a British boy with a rare genetic blood disorder would die unless his parents won permission to create a test-tube sibling who might save him.
Doctors say two-year-old Zain Hashmi needs a brother or sister with a close genetic match for a life-saving transplant or transfusion.
They have asked the authorities to relax rules over laboratory-created embryos in what would be a landmark British case.
