SBI3C College Biology Name: _______________________________ Date: ________________________________ Meiotic Cell Division MEIOSIS I MEIOSIS II Prophase I Prophase II Metaphase I Metaphase II Anaphase I Anaphase II Telophase I Telophase II Gametogensis: The Difference Between Mitosis & Meiosis Table 1: Comparing Mitotic & Meiotic Cell Division Mitotic Cell Meiotic Cell Division Division Cell type of parent (2n or n) Cell type of daughter cell(s) (2n or n) Number of daughter cells produced Genetic relationship of daughter cells to parent cells and to each other (identical or unique) Number of cell division Homework Questions 1. What is the difference between metaphase I and metaphase II? 2. What is the difference between anaphase I and anaphase II? 3. Which stage of meiosis (I or II) is most like mitosis? Explain. 4. How are haploid cells different from diploid cells in humans? 5. What is a tetrad? 6. What are homologous chromosomes? 7. Do homologous chromosomes have the same number of genes? 8. Do homologous chromosomes have identical genes? Explain. 9. What are the two key features of meiosis that contribute to genetic variations? 10. Explain why synapsis may lead to the exchange of genetic information. 11. How is crossing over different from independent assortment? 12. Compare the key similarities and differences between spermatogenesis and Oogenesis. 13. A muscle cell of a mouse contains 22 chromosomes. Based on this information, how many chromosomes are there in the following types of mouse cells? a. Daughter muscle cell formed from mitosis b. Egg cell c. Fertilized egg cell 14. When meiosis occur in females, the cytoplasm is not divided equally among the resulting four cells. Explain why. 15. Draw a diagram of meiosis to show how a female child is produced from the union of a sperm and an egg. 16. Fill in the blanks: A diploid cell undergoes _______ nuclear division(s) in mitosis. Mitosis produces ______ diploid cells. A diploid cell undergoes _________ nuclear division(s) in meiosis. Meiosis produces ______ haploid daughter cells. Generalized Life Cycle The two important processes in the life cycle of any sexually reproducing organisms are meiotic cell division and fertilization.
