The secondary spermatocytes undergo the second mitotic division to produce two equal, diploid

Step-by-step solution

Some of the spermatogonia called primary spermatocytes periodically undergo meiosis. A primary spermatocyte completes the first meiotic division leading to formation of two equal, haploid cells called secondary spermatocytes, which have only 23 chromosomes. The secondary spermatocytes undergo the second mitotic division to produce four equal, haploid spermatids. The spermatids are transformed into spermatozoa (sperms) by the process called spermiogenesis. After spermiogenesis, sperm heads become embedded in the Ser
