BBC -The headlines earlier this week that a baby had been born using DNA from three people got the world very excited – no more so than in Mexico, where the technique was carried out. The doctors used a method that takes all the vital DNA from the mother’s egg plus healthy mitochondria from a donor egg to create a new egg that’s then fertilised with the father’s sperm.
While the little boy isn’t the first baby to be created by combining DNA from three people, the method used is a new and significant one that experts say could help families with rare genetic conditions to conceive healthy babies.
