  1. Self-Check A 1. Cell undergoing mitosis or meiosis? 2. Somatic cell reproducing or gamete formation? B C 3. Chromosome count: ___ chromosomes • Structure A =? • Use the choices below for questions 4 and 5 • 5. Which best describes how A compares to B? • 6. Which best describes how A compares to C? • Same chromosome, same genes, same genetic information. • Same chromosome, same genes, different genetic information • Same chromosome, different genes, same genetic information • Different chromosomes, different genes, different info.

  2. Self-Check A B A B 7. The daughter cells of this cell will be (somatic cells/gametes). 8. Chromosome count: ___ chromosomes 9. Diploid or haploid? • For the cell above, 2n = ______; n = _______ • Structure A+B is called a ________ Use the choices below for questions 12 and 13. 12 What is the relationship b/w chromo. A and B? 13. What is the relationship b/w chromo. A and C? • Same number chromosome, same genes, same genetic information. • Same number chromosome, same genes, different genetic information/nucleotide sequence • Different chromosomes, different genes, same genetic information • Different chromosomes, different genes, different info. C C

  3. 14. Sister chromatids separate 15. Homologous chromosomes separate 16. Crossing over of non-sister chromatids in a tetrad 17. Stages in Meiosis I (more than one) 18. Stages in Meiosis II (more than one)

  4. Self Check • Chromosome #: ____ • Gender: (Male/Female) • 21. Condition: (normal/monosomy/trisomy) • If abnormal, diagnose the condition 22. What type of chromosomal mutation is shown to the left? (deletion, inversion, duplication, translocation) 23. How is this different from a genetic mutation, like a base substitution or frameshift mutation? It will effect the shape/function of one polypeptide. It will effect the shape/function of multiple polypeptides/proteins. 24. The chromosomes above (are/are not) homologous. 25. The chromosomes above are (in/not in) duplicated form.

  5. Answer Key • Mitosis • Somatic cell • 6 • Sister chromatid • A • D
