Mostly we will describe the fertilization in mammals with occasional references to sea urchins. It is true that depending upon the habitat as well as the life styles there may be variations in the fertilization process in diverse organisms. But generally the events of fertilization are more or less similar in many different organisms. Prior to the actual fusion of the sperm and the egg nuclei, the germ cells prepare themselves for the fertilization process.
