  1. Biology 393 Final Review! 2012

  2. Round 1:The Cell Cycle and Mitosis

  3. Question #1 What is the division of cytoplasm called?

  4. Question #2 Region where sister chromatids attach to one another

  5. Question #3 What is the fanlike microtubule structure called that helps direct chromosome movement?

  6. Question #4 What phase of mitosis is shown here?

  7. Question #5 What 3 phases of the cell cycle make up interphase?

  8. Question #6 What is the purpose of mitosis and cell division?

  9. Question #7 What organelle found only in animal cells sends out spindle fibers during mitosis and meiosis?

  10. Question #8 In which phase of the cell cycle does DNA replication occur?

  11. Question #1 As cells grows which increases at a greater rate the surface area or volume?

  12. Question #2 What is the difference between haploid and diploid?

  13. Question #3 During which phase of mitosis are sister chromatids separted from each other and pulled to the poles of the cell?

  14. Question #4 L x W x H tells you what about a cube?

  15. Question #5 In which phases of mitosis would you see X shaped chromosomes?

  16. Question #6 How many chromosomes are in human somatic cells?

  17. Question # 7 • What are the 3 checkpoints of the cell cycle?

  18. Round 1 Answers • cytokinesis • Centromere • Spindle • Metaphase • G1, S, G2 • Produces more cells for growth, repair and differentiation • centioles • S phase (synthesis)

  19. Round 2 • Volume • Diploid- two full sets of chromosomes, somatic cells, Haploid- only one set of chromosomes, sex cells or gametes • anaphase 4. Volume of the cube 5. Prophase and metaphase 6. 46 7. G1, G2, and Mitosis

  20. Round 3:Probability andBasic Genetics

  21. Question #1 A son gets the Y chromosome from which parent?

  22. Question #2 The actual appearance or feature that is shown for a trait is called the ________________

  23. Question #3 If a coin is tossed 3 times what is the probability of getting tails all three times?

  24. Question #4 This Mendelian Principle states that one of the alleles always overpowers the other allele.

  25. Question #5 Which trait disappeared in the F1 generation but then reappeared in the F2 generation?

  26. Question #6 Which of Mendel’s principles states that each parent can only pass on one of the two alleles they have for a trait.

  27. Question #7 The actual alleles an organism possesses for a trait is called the _______________

  28. Question #8 If you rolled a pair of dice what is the chance of getting double 6s?

  29. Question #9 Someone who shows the dominant phenotype could have which possible genotypes?

  30. Question #10 Which of Mendel’s principles explains why a tall plant with purple flowers and a short plant with white flowers could produce an offspring that is tall with white flowers?

  31. Question #11 A specific genetic characteristic that can be inherited

  32. Question #12 Mendel’s term for organisms that were the offspring of two different purebreds

  33. Question #13 If the parental genotype for two traits is AaBb what gamete combinations are possible?

  34. Question #14 A diagram used to show possible outcomes from a cross.

  35. Question #15 When two hybrids are crossed, Aa x Aa, what is the resulting genotypic ratio?

  36. Round 3 Answers: 1. The father 2. phenotype 3. ½ x ½ x ½ = 1/8 4. Principle of dominance 5. recessive 6. segregation 7. genotype 8. 1/6 x 1/6 = 1/36 9. Homozygous dominant or heterozygous 10. Independent assortment 11. Trait 12. hybrid 13. AB, Ab, aB, ab 14. Punnet square 15. 1 AA, 2 Aa, 1 aa

  37. Round 3:More Genetics

  38. Question #1 1 pair of the human chromosomes are the sex chromsomes. What are the other 22 pairs of human chromosomes called?

  39. Question #2 A picture of all the human chromosomes properly paired up is called _____________

  40. Question #3 Why are traits carried on the X chromosome more common in males?

  41. Question #4 Which type of trait typically forms a bell-curve when graphed?

  42. Question #5 If one parent has blood type AB and the other parent has blood type O what are the possible blood types for their child?

  43. Question #6 A diagram that shows inheritance patterns with in a family is called a ______________.

  44. Question #7 When homologous pairs exchange parts of their chromosome it is called ______________

  45. Question #8 If a female has a gene for an X-linked trait but does not show the trait herself she is said to be a _____________

  46. Question #9 Neither allele truly dominates and the heterozygous shows a mix of both traits

  47. Question #10 Because an individual can inherit an A, B or O allele from each parent this type of trait is called ________________

  48. Question #11 Colorblindness and hemophilia are both examples of this type of trait.

  49. Question #12 In this type of trait neither allele overpowers the other and the heterozygous shows BOTH phenotypes

  50. Question #13 What is the probabilty that these parents will have a child with O blood type? Parents: AO x AB
