Name: _______________________________________ Per. _____ Date: ______________________ Process of Meiosis Ch. 6.1 & 6.2 (pp. 168 – 176) KEY CONCEPT: During meiosis, diploid cells undergo two cell divisions that result in haploid cells. Vocabulary: 1. Sister chromatid (p. 173) – __________________________________________________________ 2. Gametogenesis (p. 176) – ____________________________________________________________ 3. Sperm (p. 176) – ___________________________________________________________________ 4. Egg (p. 176) – _____________________________________________________________________ 5. Polar body (p. 176) - _______________________________________________________________ _________________________________________________________________________________ 6. After DNA replication of the chromosomes, each identical half is called a __________________ 7. Two chromosomes that are very similar in length, shape and carry the same genes are called _____________________________________ 8. What does the sperm contribute to an embryo? _________________________________________ 9. What does an egg contribute to the embryo?____________________________________________ 10. During what phase of meiosis do homologous chromosomes separate? ______________________ 11. During which phase of meiosis do sister chromatids separate? _____________________________ 12. Refer to Figure 6.6 on page 176 and label the diagrams below: SJK Process of Meiosis Ch. 6.1 & 6.2 (pp. 168 -176) Nowicki, S. (2008). McDougal Littell biology. Evanston, IL: McDougal Littell http://msbrownnhs.sharepoint.com Use Figure 6.5 on pages 174 and 175 to complete the following diagram of the phases of meiosis. Draw 1 large homologous and 1 small homologous chromosome pair (4 sets of sister chromatids) Follow the example in the first box. Label each phase below the box.
