Detailed explanation-1: -Which outcome would be most likely if a cell failed to undergo cytoplasmic division during mitosis? The result would be one cell with no nucleus.
Detailed explanation-2: -Failures during the mitotic process or cytokinesis potentially cause the formation of cells with abnormal ploidy, such as aneuploidy or tetraploidy.
Detailed explanation-3: -Cytokinesis is the final step of mitosis in which the contents of the cell (cytoplasm and nuclei) are separated into two distinct, identical daughter cells. Mitosis without cytokinesis results in a cell with more than one nucleus but a connected cytoplasm (syncytium).
Detailed explanation-4: -If organisms did not undergo mitosis, then they would not be able to grow and replace worn-out cells. They are two of the most important cellular process in existence.
Detailed explanation-5: -Failed alignment of chromosomes leads to mitotic arrest/delay enforced by the spindle checkpoint. If the failed alignment is not corrected, cells can follow several fates. They can undergo cell death directly from mitotic arrest.
