WebGametogenesis is the process by which sperm and eggs are produced from the germ cells in the testes and ovaries, respectively. Although males and females have meiosis and differentiation as the central points of gamete formation, they differ in the timing of differentiation in relation to meiosis ( Von Stetina and Orr-Weaver, 2011 ).
