"It is actually dysgenic to assist reproductively defective women to have babies. These women are merely guinea pigs to these doctors who want subjects on which to experiment.
The possibility of a cure is not a guarantee of a cure and experiments can go wrong.
However, it is apparently not the job of MPs to consider whether such a policy would be in the national interest or whether the possibility of genetically defective babies born this way become a further burden on the state and be seen as a misfortune for their parents enticed into going along with this experiment.
Their purpose, as they see it, is to practise gesture politics and show how much they care in order to acquire as many dysgenic female votes as they possibly can, by hook or by crook."
Alana Saarinen is a thirteen year old girl who lives with her mum and dad in Michigan, USA. She loves playing golf and the piano, listening to music and hanging out with friends. In those respects, she's like many teenagers around the world. Except she's not, because every cell in Alana's body isn't like mine and yours; Alana is one of a handful of people in the world who have DNA from three people. The BBC's Science Correspondent Rebecca Morelle explores how more children like Alana could be born. This programme examines the safety and health implications of this new science. For some it is controversial. For those who have these specific genetic diseases, it is the way they could have their own healthy child. The UK is playing a pioneering role in developing the technique, called mitochondrial replacement, and Parliament has just voted to make the process legal. But despite that, there are a small number of children in the world, like Alana Saarinen, who have DNA from three people already. Although a small sample, they could answer some of the questions people have, such as will they be healthy, do they feel like they have three parents and would they like to trace the donor one day in the future?
What are MPs who vote for the amendment to the Human Fertilisation and Embryology Act 2008 hoping to achieve?
