Babies born with three rather than two parents might help in preventing genetic disorders.

Babies can be conceived with three biological parents within three years after the research gets over and this would stop children from inheriting severe diseases.

Scientists at Newcastle University have grown human embryos with a technique after merging DNA from two fertilized eggs and it is believed that this could soon be used to prevent serious genetic disorders.

The aim of this research is to avoid cellular batteries that are faulty, mitochondria, which can cause neurological, muscle conditions that can be fatal and serious heart and liver conditions, by replacing them with healthy ones from a donated embryo. The mother and father would supply 99.8 per cent of its DNA, with a small amount from another woman, the mitochondrial donor to a child that would inherit genetic material from three parents.

Doug Turnbull, who led the research, said, “It could potentially help families at risk from mitochondrial diseases to have healthy children in as little as three years, although follow-up studies are still needed.”

Reports state that one out of 200 children every year is born with genetic mutations in the mitochondria, though the effects are generally not very serious but one in 6,500 people develop incurable disease.
