Selectivity permeable membrane and a scaffold for biochemical activity
The Telophase 2 is the fourth step or process during Meiosis (cell
division). During Telophase 2, a nuclear envelope forms around each set of new

producing four daughter cells each with a haploid set of chromosomes. During
the crossing-over phase some chromosomes are observed to have segments that
have recombined with the original parent chromosomes.

When the phase is over, the two
cells are now finally separated and their nuclear membranes are fully formed
causing the meiosis cell division to be completed.</span>
