Jor genetic variation. 1. Differentiate the processes of mitosis and meiosis. 2. Describe the role of mitosis in asexual reproduction, and/or the role of meiosis in sexual reproduction, including how these processes may contribute to or limit genetic variation. 3. Describe specific events occurring in each of the stages of the cell cycle and/or phases of mitosis. 4. Explain how mitosis forms new cells and its role in maintaining chromosome number during asexual reproduction. 5. Explain how cancer (uncontrolled cell growth) may result from mutations that affect the proteins that regulate the cell cycle. 6. Describe the process of meiosis, including independent assortment and crossing over.

Oogenesis
The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.
Cell Division
Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:
