  4. Category 1 10 Crossing over Has matching areas on chromatids exchange Causes mutations Affects how traits are passed on to offspring All of these are correct

  5. Category 1 20 Gametes are indicated on a Punnet square In the boxes Along the top and sides Both a and b

  6. Category 1 20 Gametes are indicated on a punnet square In the boxes Along the top and sides Both a and b

  7. Category 1 30 Predicting the ratio of traits in offspring is easy when you use________________.

  8. Category 1 30 Predicting the ratio of traits in offspring is easy when you use ________________. Punnet Square

  9. Category 1 40 Which of these is a best match for homozygous? Different traits are present Tt AB Pure blood

  10. Category 1 40 Which of these is a best match for homozygous? Different traits are present Tt AB Pure blood

  11. Category 1 50 Explain why deadly genetic diseases are usually recessive.

  12. Category 1 50 Explain why deadly genetic diseases are usually recessive. The parents are carriers and survive to pass it to the offspring.

  13. Category 2 questions follow

  14. Category 2 10 Nondisjunction causes Homologous chromosomes (same) to stick together in Metaphase so that they do not separate during anaphase. How can this affect chromosome number?

  15. Category 2 10 Nondisjunction causes Homologous chromosomes (same) to stick together in Metaphase so that they do not separate during anaphase. How can this affect chromosome number? A gamete may have one too many or one to few chromosomes

  16. Gametes are produced during Mitosis Meiosis 20

  17. Category 2 20 Gametes are produced during Mitosis Meiosis

  18. Category 2 30 What occurs during fertilization? The egg is formed during meiosis The sperm is formed during meiosis Meiosis occurs The egg and sperm are united

  19. Category 2 30 What occurs during fertilization? The egg is formed during meiosis The sperm is formed during meiosis Meiosis occurs The egg and sperm are united

  20. Category 2 40 When is a di-hybrid cross used? Crossing 1 trait for 2 organisms Crossing 2 different traits Both a and b are correct

  21. Category 2 40 When is a di-hybrid cross used? Crossing 1 trait for 2 organisms Crossing 2 different traits Both a and b are correct

  22. Category 2 50 Cells with only one member of each chromosome are called Haploid Diploid Homozygous heterozygous

  23. Category 2 50 Cells with only one member of each chromosome are called Haploid Diploid Homozygous heterozygous

  24. Category 3 questions follow

  25. Category 3 10 What is the genotype for a homozygous tall dominate trait? Tt TT TS

  32. Category 3 40 Which is correct about the picture? The gametes are RW Red is recessive Pink flowers are hybrids with incomplete dominance Pink indicates C0-dominance

  33. Category 3 50 What is the genotype for the organisms in the square? 4 pink 4 hybrid RW incomplete dominant 2 hybrid, 2 pure 4 hybrid RW co dominant

  34. Category 3 50 What is the genotype for the organisms in the square? 4 pink 4 hybrid RW incomplete dominant 2 hybrid, 2 pure 4 hybrid RW Co-dominant

  35. Category 4 questions follow

  36. Category 4 10 How can you determine the phenotype of the horse? Doing a test-cross Produce Punnet squares Look at him

  37. Category 4 10 How can you determine the phenotype of the horse? Doing a test-cross Produce Punnet squares Look at him

  38. Category 4 20 The law of ____________________states that the inheritance of alleles for one trait is not affected by the inheritance of alleles for a different trait if the genes for the traits are on separate chromosomes Independent assortment Segregation

  39. Category 4 20 The law of ____________________states that the inheritance of alleles for one trait is not affected by the inheritance of alleles for a different trait if the genes for the traits are on separate chromosomes Independent assortment Segregation

  40. Category 4 30 Mendel’s law of _____________states that during meiosis, the factors that control each trait separate, and only one factor from each pair is/are passed to the offspring. Independent Assortment Segregation

  41. Category 4 30 Mendel’s law of _____________states that during meiosis, the factors that control each trait separate, and only one factor from each pair is/are passed to the offspring. Independent Assortment Segregation

  42. Category 4 40 Alternative forms of a trait are called a. genes b. Alleles c. Chromosomes d. gametes

  43. Category 4 40 Alternative forms of a trait are called a. b. alleles

  44. Category 4 50 In humans, brown eyes are dominant over blue. A blue eyed man marries a brown eyed women. What is the man’s genotype?

  45. Category 4 50 In humans, brown eyes are dominant over blue. A blue eyed man marries a brown eyed women. What is the man’s genotype? bb

  46. Category 5 questions follow

  47. Category 5 10 In dogs, there is an hereditary deafness caused by a recessive gene, “d.” A kennel owner has a male dog that she wants to use for breeding purposes if possible. The dog can hear, so the owner knows his genotype is either DD or Dd. If the dog’s genotype is Dd, the owner does not wish to use him for breeding so that the deafness gene will not be passed on. How can you determine its genotype?

  48. Category 5 10 A kennel owner has a male dog that she wants to use for breeding purposes if possible. The dog is either DD or Dd. How can you determine its genotype? TEST CROSS_Cross it with a recessive dd If the dominant trait is present, some of the offspring will have the trait

  49. Category 5 20 How can two hearing dogs produce deaf offspring?

  50. Category 5 20 How can two hearing dogs produce deaf offspring? Both parents were hybrids
