Cytokinesis in an animal cell:
Splitting of the cell is called cytokinesis which starts at telophase. In animal cells, microtubules form a furrow in a ring around the cell.
Mechanism:
During late telophase the astral microtubles send a signal to equatorial region of the cell, where actin and myosin are activated which form contractile ring, followed by cleavage furrow, which deepens towards the center of the cell, dividing the parent cell into two daughter cells.
