Verified step by step guidance

Understand that oogenesis is the process of forming female gametes, which involves the transformation of a primary oocyte into a mature ovum.

Recall that the primary oocyte is arrested in prophase I of meiosis until puberty, when hormonal signals trigger the continuation of meiosis.

During the first meiotic division, the primary oocyte completes meiosis I to form two cells: a larger secondary oocyte and a smaller polar body.

The secondary oocyte receives most of the cytoplasm, while the polar body receives very little, which is why it is smaller and typically does not develop further.

Recognize that the secondary oocyte will proceed to meiosis II, but it will only complete this division if fertilization occurs, resulting in an ovum and another polar body.
