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.
