Question

How many sperms are formed from a secondary spermatocyte?

Answer 1

Spermatogenesis:

1. When the undifferentiated primordial germ cells reach sexual maturity, they divide several times via mitosis to produce a large number of spermatogonia.
2. Each spermatogonium develops into a larger primary spermatocyte.
3. Each primary spermatocyte divides into two successive divisions known as maturation divisions.
4. The first division of maturation is reductional or meiotic.
5. The primary spermatocyte, hence, divides into two haploid daughter cells known as secondary spermatocytes.
6. Both secondary spermatocytes are now going through a second maturation division, which is a normal mitotic division, to produce four haploid spermatids.
7. As a result, each secondary spermatocyte produces two spermatids, which undergo transformation to form two sperms.
8. Both secondary spermatocytes produce four sperms in total.
