Answer:

Answer is 3,  The separation of sister chromatids would occur prematurely.

Explanation:

Shugoshin are known as the proteins which involve in protecting cohesiveness of sister chromatids. They prevent the removal of meiotic cohesin complexes from the centromeres at the first meiotic division. They are regarded as the guardian spirit.

They are known to be important for the completion of meiosis cell division, but not mitotic cell division.
