Science has developed ways now that an offspring can have the DNA of three parents. This is also being practiced with pending laws of this procedure in the UK. Lawmakers in the UK are approving the use of DNA of three parents in embryos of new borns. The practice of this procedure is to aid in the prevention of mitochondrial disease which causes babies born with it to have control of their muscles which scientists call "powerhouse cells" Mitochondrial bad cells would be removed and replaced with a health cell from the healthy donor's DNA. Thus making expectant parents more like to have birth of a baby without passing on the disease to the infant.
The UK is the first to make the procedure into law, however there is much opinion and some who speak against using such a procedure because of moral and or religious ethics. Other groups feel that more research is need in the procedure and that there could be problems that may development with such technique using IVF.
