In the diagram above, Process X depicts meiosis I and Process Y depicts mitosis. One of the functions of meiosis is to produce variation in the gametes formed by this process. There are two events in meiosis that contribute to genetic variation. For EACH event that contributes to variation in meiosis: i. Name the event. ii. Name the meiotic stage it occurs in and identify that stage in the diagram above. ii. Explain how the event contributes to genetic variation.
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:
