During which stage of meiosis is the secondary oocyte arrested?

Understand the Problem

The question is asking about the specific stage of meiosis during which the secondary oocyte is halted in its development. This requires knowledge of the stages of meiosis and the process of oogenesis.

More Information

The secondary oocyte is initially arrested in metaphase II after ovulation. This arrest is crucial for coordinating the timing of fertilization since completion of meiosis II only happens if fertilization occurs.

Tips

A common mistake is to confuse the arrest stage of the primary oocyte (prophase I) with that of the secondary oocyte (metaphase II).
