Question

How many sperms are formed from a secondary spermatocyte?
A).4
B).8
C.)2
D.)1
answer key says option (C) 2, why is it so?
kindly give me a clear explanation

Answer 1

At sexual maturity, the undifferentiated primordial germ cells divide several times by mitosis to produce a large number of spermatogonia. Each spermatogonium actively grows to a larger primary spermatocyte. Each primary spermatocyte 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 division which is an ordinary mitotic division to form, four haploid spermatids. Thus each secondary spermatocyte gives rise to two spermatids that undergo transformation to form two sperms. Overall, both secondary spermatocytes give rise to four sperms.

this is your answer

Answer 2

C.) 2

Explanation:

• Spermatogenesis is a process through which the haploid spermatozoa forms from the germ cells typically in the seminiferous tubules in the testis.
• This process initiates with a mitotic division in the stem cells.
• The spermatogenesis is the process of formation of the spermatid from the spermatogonia.
• The spermatogonia undergoes mitotic division and produces two primary spermatocytes and then the primary spermatocyte produces 2 secondary spermatocytes. Each secondary spermatocyte produces two spermatids or sperms.
