A new study suggests that identical twins are not exactly the same genetically. Identical twins are two babies that come from the same fertilized egg. Scientists in Iceland examined DNA from 387 pairs of identical twins, their parents, children, husbands or wives. The examinations led the team to find early mutations that separate identical twins, lead researcher and geneticist Kari Stefansson said. He is a professor at the University of Iceland and founder of the company deCODE genetics. Mutations are small changes in DNA that can happen when a cell divides in an attempt to copy itself. These small changes can influence a person’s physical appearance or control a person’s ability to fight a disease. The newly discovered mutations show that identical twins do have genetic differences, the researchers said.
