What is the three-parent protocol?
three-parent baby, human offspring produced from the genetic material of one man and two women through the use of assisted reproductive technologies, specifically mitochondrial manipulation (or replacement) technologies and three-person in vitro fertilization (IVF).

London: Britain is set to become the first country in the world to legally offer “three-parent baby” fertility treatments after regulators gave the green light.
Can a child have 2 fathers DNA?
It is possible for twins to have different fathers in a phenomenon called heteropaternal superfecundation, which occurs when two of a woman’s eggs are fertilized by sperm from two different men.
Which is the first country in the world to allow 3 parent babies?
Britain
Britain became the first country in the world to allow the creation of so-called “three-parent” babies as MPs voted overwhelmingly in favour of the controversial technique of mitochondrial donation.
What is a family of 3?
“A family of three/four/five” means two parents plus one/two/three children; or one parent + two/three/four children. So “I have a family of x” doesn’t quite work.
Can triplets have 3 different fathers?
