At the time of ovulation,secondary oocyte is arrested at Metaphase II and goes into the fallopian tube.If fertilization occurs, sperm binds with secondary oocyte and releases Anaphase promoting factor which leads to completion of meiosis II,ovum is formed and it subsequently gets converted into zygote. My question is that why formation of ovum is dependent on fertilization by sperm and why formation of sperms is independent process? Has it some benefits for nature?
