WebThe formation of a polar body allows the primary oocyte to reduce its genome by half and retain most of its cytoplasm in the secondary oocyte. The secondary oocyte still has two copies of each chromosome, so if it is to become a fully functioning ovum, it must undergo the second meiotic division. WebOogonia originating from primordial germ cells proliferate by mitosis and form primary oocytes that arrest at the prophase of the first meiotic division.
