Directions: Refer to the pictures below to answer questions #6-10 regarding Meiosis II. Directions: Refer to the picture below to answer questions 11 and 12. 11. Name and describe what is happening in the picture. 12. Which stage does this happen in? Directions: Answer each question below using your book and your notes to help you if necessary. 13. What is meiosis? 14. What is the process by which sperm are produced in males? 15. Where does spermatogenesis occur? 16. How many sperm are created at the end of spermatogenesis and are they haploid or diploid cells? 17. What is the process by which ova are produced in females? 18. Where does oogenesis occur? 19. How many eggs, or ova (plural of ovum), are created at the end of oogenesis? Directions: Put the stages of Meiosis I and II in order (write the correct letter in each blank). Also write down the name of the specific stage in the blank provided. Meiosis I: Meiosis II: 20._____ Stage:____________________ 24. _____ Stage:____________________ 21._____ Stage:____________________ 25. _____ Stage:____________________ 22. _____ Stage:____________________ 26. _____ Stage:____________________ 23. _____ Stage:____________________ 27._____ Stage:____________________ Note: Cut out the pictures and arranging them on your desk! Then keep the pictures to study for the test. It would probably be best if you staple in the corner after you have cut them out so you have a “flip book” to study stage by stage! ------------------------------------------------------------------------------------------------------------ 28. When does DNA replication occur? 29. What is an advantage of sexual reproduction? 30. What is an advantage of asexual reproduction? 31.

Meiosis _________ 33. Prophase I _________ 34. Crossing-Over _________ 35. Telephase II _________ 36. Oogenesis A. chromosomes become visible B. results in one egg cell and 3 polar bodies C. results in 4 haploid cells D. halves the number of chromosomes and results in gametes or spores E. results in exchange of chromatid portions between homologous chromosomes
