The number of spermatozoa, a single primary spermatocyte finally produced in spermatogenesis is

The correct option/answer is 4.

In spermatogenesis, the process of male gamete formation proceeds as follows:

A diploid primary spermatocyte (2n) undergoes the first meiotic division (Meiosis I) to produce two haploid secondary spermatocytes (n).

Subsequently, both secondary spermatocytes undergo the second meiotic division (Meiosis II) to form spermatids.

Each secondary spermatocyte produces two spermatids, resulting in a total of four haploid spermatids from the initial single primary spermatocyte.

These four spermatids then undergo spermiogenesis (differentiation) to mature into four functional spermatozoa.

Thus, the number of spermatozoa finally produced from a single primary spermatocyte is 4.
