Only before puberty , only before birth.

     Germ cell proliferation through mitosis in males occurs before puberty and for females it occures only before birth and stands upto meotic division 1 upto 50 years and later ovulation begins at puberty. In males, after puberty the mitotic proliferation goes for meosis.

Mitosis unfolds through a sequence of stages marked by specific events in the cell. The structural changes in the cell are about by a series of tightly coordinated underlying mechanisms. Sort each process into the appropriate bin to indicate the stage of mitosis in which it occurs. If a process occurs in more than one stage, sort it to the stage when it first occurs.
