Question

Spermatids are formed after the second meiotic division from secondary spermatocytes. The ploidy of the secondary spermatocytes is

• A. $n$
• B. $2n$
• C. $3n$
• D. $4n$

Answer 1

The correct option is A $n$

Spermatogenesis is the process by which spermatozoa or sperm cells are produced from spermatogonial stem cells through mitosis and meiosis. The spermatogonium(2n) undergoes mitosis to form primary spermatocytes(n). The primary spermatocytes divide meiotically to form the secondary spermatocyte (n) which further divide to from the spermatids(n). These spermatids mature to form the sperms(n). The ploidy of secondary spermatocytes is n(haploid). Thus the correct answer is option A.
