Scientists have found twins from a single bone of their mother and two sperm from their father. They think that two sperm fertilized the same oculus and from there twins emerged: each of them collected the chromosomes of the two sperm. The fertilization of a single egg by two sperm is very rare and the survival of the embryo and the extraction of twins is also rare. They have found them almost by chance, but they think there will hardly be another case. The news has been published in the April issue of Human Genetics magazine.
