Does meiosis in females only complete if oocyte is fertilized?

The answer is yes. Female infants are born with primary oocytes that are stalled in prophase I until puberty. At the onset of puberty, the ovaries begin oogenesis. During oogenesis, three polar bodies and one functional gamete are produced. Oogenesis is achieved through meiosis. However, the ovulated secondary oocyte arrests in metaphase II and does not complete meiosis II until it is fertilized.


Difference between primary and secondary oocyte?

Any oogonia that has arrested itself in meiosis I prophase-dipotene on the onset of OMI (oocye maturation inhibition) hormone in the 3rd month of pregnancy and there after is a primary oocyte. On the urge of Leutinizing hormone which induces the pre-ovulatory phase, the primary oocyte completes meiosis I and arrests itself in meiosis II metaphase, which would only be completed if fertilization occurs, otherwise it will degenrate in 24 hours. On the completion of meiosis I, a SECONDARY oocyte and forst polar body is going to be formed.

Are the cells diploid or haploid at the end of meiosis?

At the end of Meiosis II, which is the complete end of Meiosis, you end up with four haploid daughter cells.


Are Meiosis I and Meiosis II identical steps that follow each other?

If you mean meiosis I and meiosis II, then no they are not identical, but meiosis II does follow meiosis I.


How many cells would have been present when meiosis 2 was complete?

Meiosis is the process of replicating sex gametes. At the end of a typical meiosis phase II there are 4 cells.


Is Oocyte haploid?

Unfertilized egg is haploid; but fertilized egg is diploid. That is why you sometimes see chickens even in commercial eggs.
