<prompt> Oocyte at the time of bih, is present in which of the following stage of meiosis?Prophase IMetaphase IAnaphase ITelophase I  <response>: At Time of bih oocyteis dormant in diplotene stage resting stage during prophase I Oocyte and Prenatal period. 3rd month end 5th month 7th month Oogonia are arranged in clusters surrounded by a layer of epithelial cells. Number of germ cells in ovary reaches maximum 7 million Majority of oocyte degenerate, except few, surviving ones enter prophase I are surrounded by follicular epithelial cells forming PRIMORDIAL FOLLICLE. Oogonia enters meiosis I before bih. Hence at bih, ovary contains primary oocytes arrested in the diplotene stage of prophase I which gets completed after pubey to form secondary oocyte. This secondary oocyte is arrested in metaphase-2 stage of meiosis II which is completed when feilization occurs.
