Vedclass · Answer

(B) The secondary oocyte remains arrested in the metaphase-$II$ stage of meiosis-$II$. When the sperm comes in contact with the ovum,the acrosome releases enzymes that facilitate the penetration of the sperm through the zona pellucida and the plasma membrane. The actual entry of the sperm into the cytoplasm of the ovum triggers the completion of the second meiotic division,resulting in the formation of a haploid ovum (ootid) and a second polar body.

What induces the completion of the meiotic division of the secondary oocyte?
