According to a report, it is right that life-threatening disorders can be prevented by fertility treatment which creates embryos from two women and one man.

Genetic material from three people is there in children born through ‘three-person IVF’.

Children who are suffering from very severe and debilitating disorders could be freed by using this technique, the UK's Nuffield Council on Bioethics said.

The technique was cited as dangerous and unnecessary by other groups.

Body’s tiny power stations are mitochondria and the aim of this process is to replace faulty mitochondria. Every cell of the body contains these and that too to the tune of hundreds and sometimes thousands.

Mitochondrial DNA is seen in all of them and sometimes this can be mutated and defective.

In the UK due to this, one in 6,500 children are born with ‘mitochondrial disorder’ which causes muscle weakness, blindness and heart failure.

It is from a mother to a child that mitochondria are passed down. But in this process it is different as it takes the core genetic information from mother and father as usual, but puts it into a donor egg which contains healthy mitochondria.
