How many sperms are formed from a secondary spermatocyte?

Options

A. 4
B. 8
C. 2
D. 1

Answer

C

Explanation

At sexual maturity, the undifferentiated primordial germ cell divide several times by mitosis to produce a large number of spermatogonia. Each spermatogonium actively grows to a large primary spermatocyte. Each primary speramtocyte undergoes two successive divisions, called maturation divisions. The first maturation division is reductional or meiotic. Hence , the primary spermatocyte divides into two haploid daughter cells called secondary spermatocytes. both secondary spermatocytes now undergo second maturation dividion which is an ordinary mitotic division to form, four haploid spermatids. Thus each secodary spermatocyte gives rise to two spermatids that undergo transformation to form two superms. overall , both secondary spermatocytes give rise to four sperms.
