How “Designer Babies” works…

The Genetic Modifying of embryos is a type of in-vitro fertilization. In-vitro fertilization works by the extraction of eggs from the mother and sperm from the father. They are fertilized in a small petri dish (hence the name “test-tube babies”), and the embryo is transferred back to the mother’s uterus. A baby can be genetically modified during this process with the use of a third “parent”- who will be the donor for mitochondria inserted into the embryo. These mitochondria hold the genes of the “third parent” and will therefore be incorporated into the embryo to achieve the desired effect.
