1. Body cells, red blood cell, skin cell, brain cell 2. What type of cell undergoes meiosis? Gamete cells or Somatic cells 4. Define homologous chromosomes. 2 chromosomes with similar structure 5. For each of the following state if the cell is haploid or diploid. Sperm cell =haploid Liver cell =diploid Egg cell =haploid Stomach cell =diploid 6. If the diploid number in a liver cell of an organism is 52, how many chromosomes are there in the egg of this organism? 26 7. The fusion of sperm and a egg produces a zygote with 46 chromosomes 8. During meiosis, the chromosome number: a) is doubled b) is reduced c) remains the same d) becomes diploid 9. Meiosis produces haploid cells called gametes 10. sperm and egg- each have 23 chromosomes 11. Cells starting mitosis & meiosis begin with a (haploid or diploid) set of chromosomes. diploid 12. How many times do cells divide during meiosis? twice 13. MeiosisI: Prophase I, Metaphase I, Anaphase I, and Telophase I Meiosis II: Prophase II, Metaphase II, Anaphase II and Telophase II 14. Pairs of chromosomes lying together in Prophase I 15. Which of the following best describe the term “crossing over”? a.) An exchange of information between two homologous chromosomes b.) A molecular interaction between two sister chromatids c.) A molecular interaction between two non-sister chromatids d.) A separation of two sister chromatids 16. DNA 17. Crossing over can be found in the stage of Prophase I Figure 2 18. Which letter in Figure 2 represents meiosis? Why? D, one diploid cell becomes 4 haploid 19. How many cells are formed at the end of Meiosis I? 2 20. Is DNA copied before Meiosis II? No 21. How many cells form at the end of meiosis and how many chromosomes do they each contain? 4 with 23 chromosomes 22. Oogenesis ultimately gives rise to Four ova with Hapoid 23. A sperm cell is a (gamete or zygote), and is (haploid or diploid). 24. When a sperm cell and an ovum merge, they undergo the process of fertilization, and give rise to a zygote which is diploid 25. a. 10 b. 10 c. 5 d. 5 e. 5
