Timing of oogenesis

11.4.U1: Spermatogenesis and oogenesis both involve mitosis, cell growth, two divisions of meiosis and differentiation (Oxford Biology Course Companion page 499).

• Define oogenesis and spermatogenesis.

• Outline the processes involved in spermatogenesis within the testes, including mitosis, cell growth, the two divisions of meiosis and cell differentiation

• Outline the processes involved in oogenesis within the ovary, including mitosis, cell growth, the two divisions of meiosis, the unequal division of cytoplasm and the degeneration of polar body

11.4.U2:  Processes in spermatogenesis and oogenesis result in different numbers of gametes with different amounts of cytoplasm (Oxford Biology Course Companion page 503).

• Compare the processes of spermatogenesis and oogenesis, including the number of gametes, size of games, the timing of formation and release of gametes.
