Because you get half of your chromosomes from your mother and half from your father. 0.5 + 0.5 =1 WebThe chromosomes complete their move to the opposite poles of the cell. At each pole of the cell a full set of chromosomes gather together. A membrane forms around each set of chromosomes to create two new cell nuclei. This is the last phase of meiosis, however cell division is not complete without another round of cytokinesis.
