Read the following statements regarding oogenesis in humans: A. Oogonia are formed and multiply by mitosis after birth. B. Primary oocytes are temporarily arrested at the prophase-I stage of meiotic division. C. The first meiotic division is an unequal division resulting in a large secondary oocyte and a tiny first polar body. D. The secondary oocyte completes meiosis II prior to ovulation. How many of the above stat

Step-by-step solution

Statement A is incorrect because oogenesis is initiated during the embryonic development stage when a couple of million oogonia are formed within each fetal ovary; no more oogonia are formed and added after birth. Statement B is correct as the oogonia start division and enter into prophase-I of the meiotic division, getting temporarily arrested at that stage as primary oocytes. Statement C is correct because the primary oocyte completes its first meiotic division within the tertiary follicle. It is an unequal divis
