U.K. lawmakers voted to make Britain the first country in the world to legalize technology aimed at preventing some genetic diseases by combining the DNA of three people to create a child.
The vote came after seven years of scientific study, ethical assessment and public debate of a technique that involves replacing potentially diseased DNA from the mother with healthy genes from a donor. The decision by lawmakers must be repeated in the upper house of Parliament for the measure to become law.
