This is due to the spindle fires, which had attached to the centromeres, pulls them towards the opposite poles of the cell. While this happens, the cell membrane is already starting to pinch into itself to separate the cell.

Telophase begins once the replicated, paired chromosomes have been separated and pulled to opposite sides, or poles, of the cell.

The process of meiosis ensures genetic diversity by the crossing over and random assortment of genetic material, leading to genetically diverse offspring.

  • Chromatins condense into chromosomes

  • Centrioles start to appear

  • synapsis happens and tetrads form

  • crossing over happens (first cause of genetic variation)

  • nuclear envelope disappears

The chromosomes will later get separated into four cells with 23 chromosomes in each(46 chromatids).
