Detailed explanation-1: -An oocyte finishes meiosis I as its follicle develops (amid ovulation) bringing about an optional oocyte and the first polar body . After ovulation, every oocyte proceeds to metaphase of meiosis II. Meiosis II is finished just if treatment happens, bringing about a prepared develop ovum and the second polar body.
Detailed explanation-2: -After ovulation the oocyte is arrested in metaphase of meiosis II until fertilization. At fertilization, the secondary oocyte completes meiosis II to form a mature oocyte (23, 1N) and a second polar body.
Detailed explanation-3: -1: Oogenesis: The process of oogenesis occurs in the ovary’s outermost layer. A primary oocyte begins the first meiotic division, but then arrests until later in life when it will finish this division in a developing follicle. This results in a secondary oocyte, which will complete meiosis if it is fertilized.
