Verified step by step guidance

Understand the process of meiosis in female gametes: Meiosis is a type of cell division that reduces the chromosome number by half, creating four haploid cells. In females, this process is crucial for the formation of eggs (ova).

Recognize the stages of meiosis: Meiosis consists of two main stages, Meiosis I and Meiosis II. Meiosis I is completed before birth, and the primary oocytes are arrested in prophase I until puberty.

Identify the role of Meiosis II: After ovulation, the secondary oocyte is arrested in metaphase II. Meiosis II will only be completed if fertilization occurs.

Connect the completion of Meiosis II with fertilization: When a sperm cell penetrates the secondary oocyte, it triggers the completion of Meiosis II, resulting in the formation of a mature ovum and a second polar body.

Conclude that Meiosis II is completed at fertilization: The process of fertilization is the key event that completes Meiosis II in the female gamete, allowing for the formation of a zygote.
