Question

In oogenesis after meiosis I, which of the following is formed?

• A. Ovum and polar body
• B. Secondary oocyte and first polar body
• C. Two polar bodies
• D. Primary oocyte

Hint:

Meiosis I in oogenesis results in the formation of a secondary oocyte, which will be released during ovulation, while the polar body plays no further role in reproduction.

Answer 1

The Correct Option is B

During oogenesis, after meiosis I, the primary oocyte divides asymmetrically to form a large secondary oocyte and a smaller first polar body. The secondary oocyte then proceeds to meiosis II, while the polar body generally degenerates. Thus, the correct answer is Secondary oocyte and first polar body.
