Vedclass · Answer

(D) Fertilization is a species-specific process. This specificity is mediated by chemical interactions between the sperm and the ovum. The ovum secretes a chemical substance called 'fertilizin' (a glycoprotein),while the sperm surface contains a complementary substance called 'antifertilizin'. For successful fertilization,the fertilizin of the ovum must be compatible with the antifertilizin of the sperm. If the sperm of species $X$ cannot fertilize the ovum of species $Y$,it is because the antifertilizin of species $X$ and the fertilizin of species $Y$ are not specific to each other,preventing the necessary binding.

Sperm of animal species $X$ cannot fertilize ovum of species $Y$ because . . . . . . .
