Oogenesis produces how many ovas
WebAnswer: The fertilized egg must have enough cytoplasm to be able to divide repeatedly into the first few dozen cells of the embryo. If the female germ cell (oogonium) divided into four equal cells the way the male spermatogonium does, each resulting egg would be too small to produce a viable embr... Web17. How many ova will result from the meiosis of the sex cells of the organisms? Answer: The ovary contains many follicles composed of a developing egg surrounded by an outer layer of follicle cells. Each egg begins oogenesis as a primary oocyte. At birth each female carries a lifetime supply of developing oocytes, each of which is in Prophase I.
