Three Parents!?

10 years ago, the mother of Alana Saarinen had been unsuccessfully trying to have a baby. Doctors thought this was caused because of faulty mitochondria. So they removed the cytoplasm (with the mitochondria) of one of her eggs, and replaced it with a donor’s. This part that was replaced, however, not only produces energy for the cells, but also contains a genome with DNA. This procedure, known as mitochondrial replacing, not only gave birth to Alana Saarinen, but also gave her 3 different genes. Thats amazing! you might say. However, this procedure can have its downsides. Other babies that had transferred mitochondria haven't been as lucky. Some have mental disabilities, and in some cases, can cause miscarriages. Its still debated whether this type of birth should be allowed, since they also carry many risks. At least Alana was able to live a good and prosperous life.
