Meet the world's first 'three-parent baby': Boy - delivered by US medical team in Mexico - carries a tiny piece of genetic code from a third donor 'parent' to avoid inheriting a disease from his mother

The world's first 'three-parent' baby has been born using a revolutionary technique that combines the genes of three adults. Like all humans, the five-month-old boy carries DNA from both his parents. But he also has a tiny piece of genetic code from a donor. 


It means he has avoided inheriting a genetic condition from his Jordanian mother that could kill him by the age of two. The controversial technique has only been legally approved in the UK. However, the first baby was engineered by a US medical team who treated the woman and her husband in Mexico, where there are no laws to block the procedure. Embryologists believe this birth should fast-forward progress around the world, offering hope to millions who face the prospect of delivering terminally ill children. 'This is a milestone technique, and the possibilities are endless' Dr John Zhang, who led the medical team from New York City's New Hope Fertility Center, told Daily Mail Online.
