- Fallopian tubes (oviducts, two): receive egg from ovary; site of fertilization in ampulla region; transport developing embryo to uterus
- Uterus: pear-shaped muscular...
Q3: Describe spermatogenesis with the help of a diagram.
Spermatogenesis is formation of functional sperms from spermatogonial stem cells in seminiferous tubules of testes. Duration: 74 days approximately.
Stages:
1. Mitotic proliferation phase: spermatogonium (diploid stem cell) undergoes mitosis producing primary spermatocytes (diploid)
2. Meiotic ph...
