Miosis cell division results in the nucleus of the mother cell dividing twice in a row to form four progenitor cells , each of which contains half the number of chromosomes in the mother cell. Since the chromosomes are halved in the meiosis cell division, the chromosomes of the zygote cells are equal to the mother cells as a result of the union of male and female germ cells. If the miosis had not split in half. Then every match would have been doubled. Therefore, because of meiosis cell division, the characteristics of each species can be passed down through the generations.
