Question

What is the meiotic stage of the ovum at the time of ovulation?

Options

• First polar body at anaphase II

• Primary oocyte at prophase I

• Secondary oocyte arrested at metaphase II

• Mature ovum with completed meiosis II

Answer 1

The ovum at ovulation is actually a secondary oocyte arrested at metaphase II, not a fully mature egg. It remains in this stage until fertilization triggers the completion of meiosis II.
