1 Ch 11.4, 11.5, and 14.1 Review Game

2 What happens to the chromosome number during meiosis? A It doubles B It stays the same C It halves D It becomes diploid Ans: C

3 Gametes are A Sex cells B Sperm and eggs C Produced during mitosis D All of the above E A and B only Ans: E

4 When does crossing over occur? A Prophase I of Mitosis B Prophase I of meiosis C Telophase II of Meiosis D Prophase II of Mitosis Ans: B

5 Which of the following is used to construct a gene map? A Chromosome number B Litter count C Rate of meiosis D Recombination rate Ans: D

6 A chart that traces the inheritance of a trait in a family is called a(an) A Genome B Karyotype C Pedigree D Autosome Ans: C

7 Chromosomes form tetrads during A prophase I of meiosis B metaphase I of meiosis C interphase D anaphase II of meiosis Ans: A

8 A common genetic disorder characterized by bent and twisted red blood cells is A Cystic fibrosis B Hemophilia C Sickle cell disease D Muscular dystrophy Ans: C

9 Unlike mitosis, meiosis results in the formation of A Two genetically identical cells B Four genetically different cells C Four genetically identical cells D Two genetically different cells Ans: B

10 Meiosis results in the formation of A diploid cells B haploid cells C 2N daughter cells D body cells Ans: B

11 If two genes are on the same chromosome and rarely assort independently, A Crossing-over never occurs between the genes B Crossing-over always occurs between the genes. C The genes are probably located far apart from each other D The genes are probably located close each other. Ans: D

12 The farther apart two genes are located on a chromosome, the A less likely they are to be inherited together B More likely they are to be linked C Less likely they are to assort independently D Less likely they are to be separated by a crossover during meiosis Ans: A

13 Which of the following can be observed in a karyotype? Write all letters that apply A a change in a dna base B autosomes C sex chromosomes D Genes E Alleles F an extra chromosome G homologous chromosomes Ans: B, C, F, G

14 A human female inherits A All of the same genes that a human male inherits B Twice as many sex chromosomes as a human male inherits C One copy of every gene located on the Y chromosome D Two copies of every gene located on the X chromosome Ans: D

15 Sickle cell disease is caused by a A Change in one DNA base. B Change in the size of a chromosome. C Change in two genes. D Change in the number of chromosomes in a cell. Ans: A

16 Compared with normal hemoglobin, the hemoglobin of a person with sickle cell disease A is longer B is shorter C has a different sequence of amino acids D is wider Ans: C

17 #7 p the illustration represents what stage of meiosis? A Prophase I B Anaphase II C Telophase I D Metaphase I Ans: D

18 People who are heterozygous A They are very likely to get malaria B They usually have some normal hemoglobin in their red blood cells. C Their abnormal hemoglobin usually doesn t cause their red blood cells to become sickle shaped. D They do not produce abnormal hemoglobin. Ans: B for sickle cell disease are generally healthy because

19 To maintain the chromosome number of an organism, the gametes must A Become diploid B Become recessive C Be produced by mitosis D Be produced by meiosis Ans: D

20 A gene map shows A The number of possible alleles for a gene B The relative locations of genes on a chromosome C Where chromosomes are in a cell D How crossing-over occurs Ans: B

21 #8 on p. 285 A B C D Ans: D

22 #7 on p. 285 A B C D Ans: B
