Question

Find out the CORRECT sequence of spermatogenesis.

Options

• Spermatogonia → Secondary spermatocytes → Primary spermatocytes → Spermatids → Sperms

• Spermatids → Spennatogonia → Primary spermatocytes → Secondary spermatocytes → Sperms

• Spermatogonia → Spennatids → Primary spermatocytes → Secondary spermatocytes → Sperms

• Spermatogonia → Primary spermatocytes → Secondary spermatocytes → Spermatids → Sperms

Answer 1

Spermatogonia → Primary spermatocytes → Secondary spermatocytes → Spermatids → Sperms

Explanation:

Diploid Spermatogonia undergoes growth and forms primary spermatocytes due to the accumulation of food. Primary spermatocytes under goes first meiosis to form '.! haploid secondary spermatocytes which in turn completes second meiosis to form 4 haploid spermatids. It undergoes functional transformation to form spermatozoa.
