      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??

      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??

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

    • @Meenaz-hi5yx
      @Meenaz-hi5yx 4 ปีที่แล้ว

      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

    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.
