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:
Step by step
Solved in 3 steps
- Identify the major events that occur in each phase of meiosis AND draw a labelled diagram.Distinguish between the following terms: somatic cell and gamete; autosome and sex chromosomes; haploid and diploid. Describe the events that characterize each phase of meiosis. Describe three events that occur during meiosis I but not mitosis. Name and explain the three events that contribute to genetic variation in sexually reproducing organisms.Determine if the cells in prophase I of meiosis are haploid or diploid.
- Determine if prophase I of meiosis contains 2 chromatids or only one chromatid.Research a disease or defect that occurs in one of the stages of meiosis (cancer, Down Syndrome, non-disjunction, etc) Address the following: What changes occur during meiosis that lead to or are caused by this disease? Make sure you highlight the changes that occur during whichever specific stage of meiosis is disrupted vs what would normally happen. Is there currently any way to treat it? At what point in time can you determine if this disease is present? How?explain how the Law of Segregation and the Law of Independent Assortment relate directly to chromosome movements during meiosis. Which particular stages of meiosis demonstrate each of these two laws?
- There are two processes in meiosis that contribute to genetic variation. Name each process. Identify the meiotic stage it occurs in, and identify that stage in the diagram above. Explain how each event contributes to genetic variation. 1 2 Name of the Processes Stages in Meiosis Diagram Numbers Explanationdescribe the stages of meiosis and contrast meiosis withmitosis;Determine if the cells in prophase II of meiosis are haploid or diploid.
