Lawmakers in the U.K. have voted to allow doctors to create babies about against for from in of with the DNA about against for from in of with three different people. It will be the first country about against for from in of with the world to do this. There was a vote about against for from in of with Britain's parliament, where 382 lawmakers voted about against for from in of with allowing three-person babies and 128 voted about against for from in of with the idea. The idea behind three-person babies is to stop diseases being passed about against for from in of with a mother to her newborn baby.
