A donkey and a mule have different chromosome numbers. When meiosis occurs (the creation of egg and sperm) the chromosome numbers halve and half of the genetic material is given to each of the two new cells created. However in the case of mule, their normal body cells have an uneven chromosome number so this cannot occur, therefore they can't make eggs or sperm
