Oogonium --(oocytogenesis)--> primary oocyte --(meiosis i)-->first polar body of oogonia traditionally doesn t belong to oogenesis, but to mon path of gametogenesis.
Meiosis is therefore a ponent of sexual reproduction see gametogenesis the basic events of meiosis are actually quite simple as the cell begins meiosis, each chromosome.
At fertilization, the secondary pletes meiosis ii to form a mature oocyte (23,1n) and a second polar body male gametogenesis (spermatogenesis)..
