Question

Ova are released from ovary under the effect of LH-Hormones, after which of the following event.

• A. Before meiosis and production of polar body
• B. Meiosis-I and before production of polar body
• C. Meiosis and at the time of production of polar body
• D. Meiosis II and after the formation of polar body

Answer 1

The correct option is D Meiosis II and after the formation of polar body

Primary oocyte undergoes meiosis 1 and the first polar body and secondary oocyte are produced. Secondary oocyte which is arrested at metaphase 2 develops into the graffian follicle and after the secretion of the LH hormone occurs which leads to ovulation.

So the correct option is 'meiosis II and after the formation of the polar body'.
