11. Only the oocyte undergoes meiosis and contributes DNA to the next generation. 12. Acrosin digests the zona pellucida and membrane of the oocyte . 13. Spermatocytes develop from the transformation of choanocytes and oocytes arise from archeocytes. 14. Once the follicle is mature, it ruptures and releases the oocyte . 15. Primary oocytes will undergo oogenesis in which they enter meiosis. 16. Oocyte donation is an alternative for patients with Turner syndrome.17. The picture depicts a secondary oocyte becoming a mature ovum after meiosis. 18. Thus, Mozambique tilapias arrest oocyte growth during mouthbrooding to conserve energy. 19. LSD1 is a differentiation, as well as oocyte growth. 20. These then begin meiosis to form the oocyte within the primordial follicle.
