Solution
The correct option is C 4
Spermatogonium or primary spermatocytes produces two equal, haploid cells, called as secondary spermatocytes by first meiotic division. The secondary spermatocytes then produce four equal, haploid spermatids by second meiosis. By the process of spermiogenesis, spermatids are transformed into spermatozoa. After spermiogenesis, mature sperms are finally released from the seminiferous tubules by the process called as spermiation. Thus, the correct answer is option C.

(a) About 300 million spermatozoa may be present in a human male ejaculation at one time. Calculate how many spermatocytes will be involved to produce this number of spermatozoa.Join BYJU'S Learning Program
