Question

Must cytokinesis always follow karyokinesis? What happens if it does not?

Answer 1

You end up with a multinuclear cell (called a "syncitium")

This is usually bad, and can cause cancer and similar disorders. But in some biological systems, it is the norm: during Drosophila fruitfly development, the fertilised egg undergoes karyokinesis repeatedly, resulting in a multinucleate syncitium. Subsequently, the egg undergoes a modified cytokinesis - separating the nuclei into many seperate single-nucleated cells.

Answer 2

Yes, normally cytokinesis follows karyokinsis. If it does not happen, the cell will have two nuclei.
