Everything you wanted to know about '3-parent' babies | New Scientist
How much DNA comes from each person?
Almost all of the boy's DNA will come from his mother and father. That's because most of our genes – around 20,000 in total – are found in the cell's nucleus; just 37 are found in the mitochondria. In the new procedure, Zhang's team removed the nucleus from one of the mother's eggs and inserted it into a donor egg, which had its own nucleus removed. This egg was then fertilised with the father's sperm. The resulting embryo therefore had nuclear DNA from its parents and mitochondrial DNA from the donor.
