12

Answer 2

Spermatogenesis is the developmental process which leads to the production of male gametes, termed spermatozoa or sperm. Spermatogonial stem cells divide by mitosis to form primary spermatocytes. The primary spermatocyte is initially diploid and undergoes meiosis. After the first meiotic division, the resulting daughter cells are termed secondary spermatocytes. These undergo the second meiotic division giving rise to haploid spermatids
