Q. The correct sequence of spermatogenetic stages leading to the formation of sperms in a mature human testis is:
A) spermatogonia → spermatocyte → spermatid → sperms
B) spermatid → spermatocyte → spermatogonia → sperms
C) spermatogonia → spermatid → spermatocyte → sperms
D) spermatocyte → spermatogonia → spermatid → sperms
Explanation
[Solution from source] Spermatogonia divide by mitosis and grow into primary spermatocytes, which undergo meiosis to form secondary spermatocytes and then spermatids; spermatids change into sperms by spermiogenesis. Spermatids come after spermatocytes, so any sequence placing spermatid earlier is wrong. Answer (1).
