The correct sequence of spermatogenetic stages leading to the formation of sperms in a mature human testes is:
spermatogonia-spermatocyte-spermatid- sperms
spermatid-spermatocyte-spermatogonia- sperms
spermatogonia-spermatid-spermatocyte-sperms
spermatocyte-spermatogonia-spermatid-sperms
As we discussed in concept
Spermatogenesis -
In testis, the immature male germ cells (spermatogonia) produce sperms by spermatogenesis.
- wherein
spermatogenesis begins at puberty
Primary and secondary spermatocytes -
Primary spermatocytes periodically undergo meiosis. A primary spermatocyte completes the first meiotic division (reduction division)
leading to formation of two equal, haploid cells called secondary spermatocytes, which have only 23 chromosomes each.
-
Spermatids -
The secondary spermatocytes undergo the second meiotic division to produce four equal, haploid spermatids
-
Option 1)
spermatogonia-spermatocyte-spermatid- sperms
This option is correct.
Option 2)
spermatid-spermatocyte-spermatogonia- sperms
This option is incorrect.
Option 3)
spermatogonia-spermatid-spermatocyte-sperms
This option is incorrect.
Option 4)
spermatocyte-spermatogonia-spermatid-sperms
This option is incorrect.
