TWINS
      There are two groups of twins:identical       twins and non identical twins.
      The identical twins are not the same           but they are similar so the term               identical would be bad express.

      How identical twins happen
      It happens when a fertilized egg splits into two separate babies


      
      Something about they

      Identical twins share the same DNA but do not have the same DNA

      Every case of identical twins are two boys or two girls but there have been like three or five cases that was identical twins one girl and one boy that occurs because one of the twins loose the chronosom.
