MCQ
The process of formation of ova is called:
- AOvulation
- BOviparous
- COogenesis
- DNone of the above
Explanation:
Oogonia develops into the primary oocytes.
In meiosis I the primary oocyte forms a polar body and a secondary oocyte.
After meiosis I, the haploid secondary oocyte initiates meiosis II.
When meiosis II is completed, an ootid and another polar body is created.
Polar bodies degenerate at the end of meiosis II, leaving only the ootid that develops into a mature ovum.
