Q.88
Sertoli cells possess maximum cyst volume during which stage of meiosis prophase of during spermatogenesis?
- Cystic Spermatogenesis in Anamniotes:
- In teleosts, spermatogenesis occurs within discrete spermatocysts formed by cytoplasmic processes of Sertoli cells enclosing a synchronous clone of developing germ cells.
- During the prolonged pachytene stage of Meiosis Prophase I (when homologous chromosome synapsis and crossing over occur), primary spermatocytes undergo substantial cellular enlargement (hypertrophy) and active transcription.
- Consequently, Sertoli cell cysts reach their maximum cyst volume during the pachytene stage.
- nalysis:
- (Pachytene): Correct.
Correct option: (3) Pachytene
