Answer
First event
- Diploid spermatogonia undergo mitosis in seminiferous tubules.
- Mitotic daughter cells either remain spermatogonia or migrate to lumen as primary spermatocytes.
- Diploid primary spermatocytes pause at prophase I of meiosis.
- Haploid secondary spermatocytes are produced.
- Secondary spermatocytes undergo meiosis II.
- Haploid spermatids are produced.
- Continued differentiation during spermiogenesis yields mature haploid sperm cells.

In gametogenesis in both human males and females: (Select all that apply.) diploid stem cells are the precursors to haploid gametes. secondary spermatocytes and secondary oocytes undergo both meiotic divisions in quick succession to produce mature gametes secondary spermatocytes and secondary oocytes form by meiosis from primary spermatocytes and primary oocytes. stem cells form during embryonic development and divide by mitosis. all primary spermatocytes and primary oocytes divide by meiosis.
