In vertebrate animals, spermatogenesis and oogenesis differ, in that 1.) Cytokinesis is unequal in oogenesis whereas it i equal in spermatogenesis 2.) spermatogenesis is not completed until after fertilization occurs, but oogenesis is completed by the time a girl is born 3.) Oogenesis produces four haploid cells, whereas spermatogenesis produces only one functional spermatozoon 4.) Oogensis ends at menopause. Whereas spermatogenesis is finished before birth 5.) Oogensis begins at the onset of sexual maturity whereas spermatogenesis happens in embryonic development

There are 6 major events in fertilization. Discuss the process of fertilization or conception, with emphasis on the sperm-egg interaction. Proteins on the sperm plasma membrane bind to ZP3 molecules within the zona pellucida of the egg. Why is this event important? Zona binding triggers the acrosome reaction, in which the sperm plasma membrane fuses with the outer acrosomal membrane, causing exocytosis of acrosomal contents. What is in the "acrosomal content"? Acrosomal enzymes begin to dissolve a hole in the zona pellucida. This enzymatic degradation, accompanied by rapid sperm tail beating, moves the sperm through the zona. Where does the sperm intend to reach?
