Answer is the ovary
Explanation: the process by which egg is produced is called oogenesis. It involves the mitotic division of the primodial germ cells to from a oogonia. The oogonia becomes enveloped by follicle cells . Oogonia grows to become the primary oocyte. Each primary oocyte is diploid. It then undergoes the first meiotic division to form the secondary oogonia and a smaller polar nody. all this process of development occurs in the ovary.
After it is released from the ovary, fertilization occurs and it undergoes the second meiotic division to from a polar body and an ovum.
The primary oocyte however remains in prophase of meiosis l throughout childhood.
