Question

In human female, the ovum is released from the Graafian follicle at this stage

• A. Primary oocyte
• B. Secondary oocyte
• C. First polar body
• D. Ootid

Hint:

Ovulation releases the Secondary Oocyte. Fertilization produces the Ootid/Zygote.

Answer 1

The Correct Option is B

Step 1: Oogenesis Process:
During oogenesis in humans:
The primary oocyte completes Meiosis I within the tertiary follicle to form a large Secondary oocyte and a tiny First polar body.
The secondary oocyte proceeds to Meiosis II but arrests at Metaphase II.
It is at this stage (Secondary oocyte) that the Graafian follicle ruptures and releases the gamete during ovulation.
Meiosis II is completed only after the entry of sperm (fertilization).

Step 2: Final Answer:
The released "ovum" is technically a Secondary oocyte.
