The correct sequence of spermatogenetic stages leading to the formation of sperms in a mature human testis is:

Explanation

The correct option is: a) Spermatogonia - spermatocyte - spermatid - sperms.Explanation of each option:a) Spermatogonia - spermatocyte - spermatid - sperms:This is the correct sequence of spermatogenetic stages leading to the formation of sperms in a mature human testis. The process of spermatogenesis involves several stages of cell division and differentiation, starting with spermatogonia (diploid stem cells in the testes), which undergo mitosis and develop into primary spermatocytes (diploid cells). Primary spermatocytes then undergo meiosis I to produce secondary spermatocytes (haploid cells). Secondary spermatocytes further undergo meiosis II to form spermatids (haploid cells). Finally, spermatids undergo further maturation, including structural changes and the development of a flagellum, to become mature spermatozoa (sperms).b) Spermatid - spermatocyte - spermatogonia - sperms:This sequence is not correct. It starts with spermatid (haploid cell), which is a later stage in spermatogenesis, and then proceeds backward to spermatocyte and spermatogonia, which is the reverse order of the correct sequence.c) Spermatogonia - spermatid - spermatocyte - sperms:This sequence is also not correct. It starts with spermatogonia (diploid stem cells) and then jumps to spermatid (haploid cell) before proceeding to spermatocyte and sperms. The correct sequence has spermatid after spermatocyte.d) Spermatocyte - spermatogonia - spermatid - sperms:This sequence is not correct. It starts with spermatocyte (diploid cell), then moves to spermatogonia (diploid stem cells) before proceeding to spermatid and sperms. The correct sequence has spermatogonia before spermatocyte.In summary, option (a) Spermatogonia - spermatocyte - spermatid - sperms is the correct sequence of spermatogenetic stages leading to the formation of sperms in a mature human testis.
