What Is Monospermic and Polyspermic Fertilization?

Unlike physiological polyspermy, monospermic fertilization deals with the analysis of the egg calcium waves, as this is the typical reproduction process in all species. Species that undergo physiological polyspermy have polyploidy-preventing mechanisms that act inside the egg.

What is Monospermic fertilization?

Abstract--To elucidate whether monospermy or polyspermy is the normal mechanism during fertilization in Chrysopa carnea, the number and behaviour of the fertilizing spermatozoa were studied in eggs of this species. ... It seems that monospermic fertilization could be more frequent in insects than currently assumed.
