Quizplus · Accepted Answer

During oogenesis, one primary oocyte yields one mature ovum. This happens through meiosis I and meiosis II, resulting in the formation of one functional haploid ovum containing 23 chromosomes. Thousands of primary oocytes are formed during fetal development, but only a small number of these will mature and be released during a woman's reproductive years.
