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

Following meiosis I in oogenesis, the primary oocyte undergoes unequal division, yielding a substantial secondary oocyte and a diminutive first polar body. The secondary oocyte advances to meiosis II, whereas the polar body typically disintegrates. Consequently, the correct identification is Secondary oocyte and first polar body.
