What is the result of the second meiotic division of the secondary spermatocytes?
Options
- AFormation of two equal, haploid spermatids
- BFormation of four equal, haploid spermatozoa
- CFormation of two equal, diploid primary spermatocytes
- DFormation of two unequal, haploid spermatids
Correct answer
B. Formation of four equal, haploid spermatozoa
Step-by-step solution
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 undergo the second meiotic division to produce four equal, haploid spermatids. The spermatids are transformed into spermatozoa (sperms) by the process called spermiogenesis. After spermiogenesis, sperm heads
