Once a healthy biological male has reached adulthood, do his cells continue to divide by both mitosis and meiosis? Outline when each type of cell division might occur. In your answer, ensure you give details of: the type of tissue which is produced by mitosis, and what can start this process; - the type of tissue which is produced by meiosis, what can start this process.    asap please

Each box contains sex chromosome complements. An “O” means no sex chromosomes. Match each box to the correct stages of normal or abnormal oogenesis or spermatogenesis.
