The video tutorial explains oogenesis, the process by which females produce an ovum. It compares oogenesis to spermatogenesis, highlighting its complexity. The tutorial covers the stages of meiosis, starting with the diploid oogonium, and explains DNA replication and ploidy. It describes the arrest of the primary oocyte in prophase 1, which resumes after puberty, leading to the formation of a secondary oocyte and polar bodies. The secondary oocyte is arrested in metaphase 2 until fertilization, when meiosis 2 completes, resulting in a zygote.
