What is the result of the first meiotic division of a primary spermatocyte?
Options
- AFormation of two equal, haploid spermatids
- BFormation of four equal, haploid spermatozoa
- CFormation of two equal, diploid secondary spermatocytes
- DFormation of two unequal, haploid spermatids
Correct answer
C. Formation of two equal, diploid secondary spermatocytes
Step-by-step solution
The spermatogonia (sing. spermatogonium) present on the inside wall of seminiferous tubules multiply by mitotic division and increase in numbers. Each spermatogonium is diploid and contains 46 chromosomes. Some of the spermatogonia called 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. The secondary spermatocytes u
