Thank you 😊 sir

[@ganeshsuryawanshi4394]

Thank you so much sir 👌👌

[@princerajyadav4771]

Pls answer....sir had said that germinal epithelium will produce 2 million oogonium in each ovary..and after oogonium is formed it will undergo mitosis to form primary oocytes....2 million is already formed by germinal epithelium and if it will undergo mitosis there will be 4 million primary oocytes??so plss answer that after oogonium is formed it will go mitosis or simply differentiate into primary oocytes??

[@princerajyadav4771]

If 2 million oogonium is formed by germinal epithelium and then if it will undergo mitosis there will be 4 million oogonium in each ovary....bt there should be only 2 million ......then oogonium will undergo mitosis or simply 2million oogonium will differentiate into primary oocytes?? Answer pls

[@SakshiSingh-hy2bg]

I was confused regarding this topic thank you sir for your explanation....... it helped me a lot

[@nikhilmaurya4669]

16:00 But in books,it is written that polar body has very less cytoplasm

[@Meenaz-hi5yx]

Indeed coz primary oocyte unndergoes unequal cytokinesis due to which equal nucleus is decided between the two bt secondary oocyte receives more cytoplasm ,thus comparatively polar body has less cytoplasm and further degenerated after some time

[@shreyassmadane6020]

Thank you for your hardwork in Explaining the Topic sir. Really got it well.

[@naziyaqurashi6603]

Super explanation sri keep it up for us

[@satishganta2186]

u said (16:03) polar body does not have a nucleus. It's a wrong statement. They do have a nucleus but very little cytoplasm. That's why they degenerate.

[@dr.mitochondria98]

@@princerajyadav4771 Yes!! U r right actually I missed it...Oogonia are present before the birth and they perform mitosis to form several oogania (2n) which are 2 M I think and further these oogonia starts division and enter into prophase 1 of meiosis and there the oocytes get arrested in diplotene stage ... I think this might b the procedure if I M not wrong😅 And as sir has written germinal cell is egg mother cell and egg mother cell is OOGONIA itself Sooooo......😶
