So that means during s phase, we double the number of chromatids. Now, once our gametocides actually undergo the process of sphase, those gametocides are known as primary gametosides. So our male gametocides are known as primary spermatocides, while our female gametocides are known as primary oocytes. Now, before the female organism, before the female human is actually born, all the oocytes basically become primary gametocytes or primary oocytes. And we and we'll talk more about that when we'll discuss the process of sexual reproduction. Now, let's actually get into the process of meiosis.
