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
- Match the phase of cell division with the following diagrams. In these cells, 2n = 4. a. anaphase of meiosis I b. interphase of mitosis c. metaphase of mitosis d. metaphase of meiosis I e. metaphase of meiosis IICompare meiotic anaphase I with meiotic anaphase II. Which meiotic anaphase is most similar to the mitotic anaphase?Crossing over occurs mainly during this phase of meiosis: Prophase I Prophase II Metaphase I Metaphase II
- Identify the stages of meiosis described by the following meiotic events/conditions/terms. Write prophase I, metaphase I, anaphase I, telophase I, prophase II, metaphase II, anaphase II, or telophase II. In case the events are found in both stages, write the stages both. 1. Separation of homologous chromosome 2. Four haploid daughter cells are formed.Identify the stages of meiosis described by the following meiotic events/conditions/terms. Write prophase I, metaphase I, anaphase I, telophase I, prophase II, metaphase II, anaphase II, or telophase II. In case the events are found in both stages, write the stages both. 1. Formation of chiasma 2. Each chromatid is considered as full-fledged chromosome. 3. Chromosomes begin to pair off. 4. Spindle microtubules start to attach to the centromere. 5. Tetrads are aligned at the middle of the cell. 6. The sister chromatids separate. 7. Produce 2 haploid daughter cells. 8. The chromosomes line up at the middle of the cell. 9. The sister chromatids move together to the opposite poles. 10. The chromatids reach the poles. 11. The chromosomes in each daughter cell are still duplicated.12. Spindle microtubules attach in the centromere of each haploid daughter cell. 13.During which stage of Meiosis does crossing-over occur? O Prophase II O Metaphasel O Anaphase I| O Prophase I
- Describe the differences between the chromosomalcombinations of a cell at metaphase I and metaphase IIof meiosis.Draw the chromosomes of each daughter cell after Meiosis II:During which stage of meiosis would you find a cell with a diploid chromosome number and homologous chromosome pairs are crossed over? telophase I metaphase I anaphase I prophase II anaphase II
