British scientists have requested that the public formulate an opinion regarding the creation of IVF babies with 3 genetic parents as it is currently illegal to tamper with inherited genetic material in clinics. Having three genetic parents would prevent a wide array of diseases by using donated, healthy DNA. This would be accomplished through the donation of healthy mitochondrial DNA, where the

baby would have a full compliment of nuclear DNA from its mother and father, plus a tiny amount of donated mitochondrial DNA.”

Mitochondria have their own set of DNA separate from the rest of our body that is only passed on by women. When mitochondrial DNA is defective, it leads to diseases such as

muscular dystrophy and conditions leading to the loss of hearing and vision, heart problems and intestinal disorders.”

In order for this form of DNA donation therapy to occur, society must accept the ethical, and overly hindering, religious implications. Personally, if I was given the option of being viewed in a potentially negative way, or not having muscular dystrohpy, I would choose societal judgement every time. Dr. Geoff Watts agrees saying it

could offer significant health and social benefits to individuals and families, who could potentially live their lives free from what can be very severe and debilitating disorders.

The Telegraph’s article Give ‘three-parent’ IVF babies the green light, say ethicists also states that he

argued the genetic contribution from the second woman was so small – just 0.01 per cent – that she could not be considered a third parent, legally or biologically.

So that solves the legal issue and many potential health issues.
