Vedclass · Answer

(B) During fertilization, a sperm comes in contact with the $Zona$ $	ext{pellucida}$ layer of the ovum and induces changes in the membrane that block the entry of additional sperm.This ensures that only one sperm can fertilize the ovum, a process known as polyspermy block.Therefore, the $Zona$ $	ext{pellucida}$ acts as a primary barrier to prevent polyspermy.

During human fertilization, which of the following induces changes and acts as a barrier to ensure that only one sperm can enter and fertilize the ovum?
