1 Mitosis –vs- Meiosis Test Review

2 If the HAPLOID number of an organism is 12, what would the diploid number be? 24

3 Gametes are produced by the process of Meiosis

4 The following is a picture of Crossing over

5 Chromosomes form tetrads during Prophase 1

6 Crossing over occurs much more in meiosis than in mitosis. Which of the following is the likely reason? A. There are no tetrads with mitosis. B. There is no prophase with mitosis. C. There are no chromosomes present. The answer is A!!!!!!!!!!!!!!!!!!!!!!!!!!!!

7 Meiosis results in #? (haploid / diploid) cells. 4 haploid

8 Mitosis results in #? ________ cells. 2 diploid

9 Mitosis goes through ___ division. 1

10 Meiosis goes through ___ divisions. 2

11 _______________ cells go through meiosis. Gametes (sperm, egg)

12 True or False: Liver, Nerve and Muscle cells DO NOT divide after maturity. TRUE

13 True or false In meiosis, all four daughter cells are genetically identical to the parent cell. FALSE

14 True or False You receive half of your chromosomes from mommy and half from daddy. TRUE

15 In what stage of meiosis does crossing over happen? Prophase 1

16 In what stage of meiosis do the sister chromatids separate? Anaphase 2

17 In what stage of meiosis do the homologous chromosomes line up in the middle? Metaphase 1

18 In what stage of meiosis do the sister chromatids line up in the middle? Metaphase 2

19 In what stage of meiosis do the homologous chromosomes separate? Anaphase 1

20 Why is meiosis important? Genetic Variety/diversity

21 Haploid means there are _?_ set(s) of chromosomes. 1(n)

22 Diploid means there are _?_ set(s) of chromosomes. 2(n)

23 Female sex chromosomes are homologous _?_ (letters that represent female) XX

24 Male sex chromosomes are homologous _?_ (letters that represent male) XY

25 46, 46, all others 23

26 What stage of mitosis? Couldnt get pictures on here so study your drawings paper. Also study your Venn Diagram and both Webquests (the ones I told you in class)
