I know sometimes meiosis can occur in error, i.e. some cells are left with an extra chromosome which can lead to disorders such as down syndrome. Prior to meiosis, however, animal cells undergo mitosis and cytokinesis. Mitosis occurs when the nucleus splits, and cytokinesis occurs when the cytoplasm, or essentially the rest of the cell splits. It appears to be generally accepted that the 2 occur in sync. But I wonder if mitosis could just occur without cytokinesis occuring? Like could the nucleus just spit into 2 (mitosis), but the cytoplasm still remain intact, resulting in a single cell with 2 nuclei? And if so what would be the results of such an occurence?
