Detailed explanation-1: -Mitosis without cytokinesis results in a cell with more than one nucleus but a connected cytoplasm (syncytium). A multinucleated cell is one with several nuclei. This might be a normal occurrence. Humans, for example, have multinucleated bone cells (osteoclasts) that originate in this manner.

Detailed explanation-2: -Cytokinesis failure leads to both centrosome amplification and production of tetraploid cells, which may set the stage for the development of tumor cells.

Detailed explanation-3: -Mitosis Can Occur Without Cytokinesis Although nuclear division is usually followed by cytoplasmic division, there are exceptions. Some cells undergo multiple rounds of nuclear division without intervening cytoplasmic division.

Detailed explanation-4: -Result: Hence, the formation of two daughter cells that are identical to parental cells is the result of mitosis and cytokinesis.

Detailed explanation-5: -Cytokinesis accompanies the division of genetic material in mitosis and meiosis to physically separate the cells. If cytokinesis did not happen, multinucleated cells would form. That is, cells would have multiple nuclei (formed from mitotic divisions) but one single cytoplasm (due to the lack of cytokinesis).
