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 usually, but not always, follows mitosis. If a cell undergoes mitosis and not cytokinesis, this would result in 2 cells without nuclei O a cell with two or more nuclei. cells with abnormally small nuclei. a cell with a single large nucleus.

Detailed explanation-3: -Cytokinesis usually follows mitosis.

Detailed explanation-4: -In a typical cell, cytokinesis accompanies every mitosis, although some cells, such as Drosophila embryos (discussed later) and vertebrate osteoclasts (discussed in Chapter 22), undergo mitosis without cytokinesis and become multinucleate.

Detailed explanation-5: -If nuclear division is not followed by cytokinesis, then a cell with 2 nuclei is formed.
