Compare spermatogenesis and oogenesis.

Which statement correctly compares spermatogenesis and oogenesis in humans?

A student observes that one spermatogonium undergoes spermatogenesis to produce four functional sperm, while one oogonium undergoing oogenesis produces only one functional ovum. Identify one similarity and one difference between spermatogenesis and oogenesis.

A student is investigating gametogenesis in mammals. During spermatogenesis in a healthy adult male, approximately 300 million sperm are produced daily, with each spermatogonium undergoing continuous meiotic divisions. In oogenesis, a female is born with approximately 1–2 million primary oocytes, most of which remain arrested in prophase I of meiosis until puberty, and only one oocyte typically completes meiosis each menstrual cycle. Identify one similarity and one difference in the timing of meiotic divisions between spermatogenesis and oogenesis.
