B) a block to polyspermy
C) multiple sperms penetrating the ovum

Question

Quizplus · Accepted Answer

Multiple sperms penetrating the ovum is not a characteristic of fertilization. Fertilization occurs when a single sperm penetrates the ovum and fuses with its nucleus, leading to the formation of a zygote. The presence of multiple sperms penetrating the ovum would result in polyspermy, which is prevented by various mechanisms such as the fast block and slow block to polyspermy. A sperm's fertilin proteins binding to the ovum's integrin molecules is one of the molecular mechanisms that facilitate the binding and fusion of the sperm and ovum during fertilization.
