Web7. Second meiotic division gives rise to (a) Primary spermatocytes (b) Secondary spermatocytes (c) Spermatids (d) Spermatozoa (e) None 8. The chromosome number is halved at (a) Spermatogonium to primary spermatocyte (b) Primary spermatocyte to secondary spermatocyte (c) Secondary spermatocyte to spermatid (d) Spermatid to sperm WebEach primary spermatocyte undergoes meiosis I to produce two equally sized secondary spermatocytes (n). Each secondary spermatocyte then undergoes meiosis II to produce a total of four spermatids (n). The spermatids differentiate before moving to the epididymis. Oogenesis, on the other hand, begins prior to birth and is a stop-start process.
