37. Claire has curly hair which is a recessive trait (h). What is Claire’s phenotype? A: curly hair 16 - Answer

38. Claire has curly hair which is a recessive trait (h). What is Claire’s genotype? 17

39. Claire has curly hair which is a recessive trait (h). What is Claire’s genotype? A: hh 17 - Answer

40. Curly haired Claire falls in love with homozygous Henry who has straight hair (H). Will any of their children be purebred? Why or why not?? 18

41. A: No. 100% of their children will be hybrid and will have straight hair (Hh). Henry Claire H = Straight hair h = curly hair H H h hHh 18 - Answer Hh

42. In Mendel’s experiments, what percent of the offspring in the first generation showed the dominant trait? What is the dominant trait? 19

43. In Mendel’s experiments, what percent of the offspring in the first generation showed the dominant trait? A: 100% - all of the offspring were purple 19 - Answer

44. In Mendel’s experiments, what percent of the offspring in the first generation carried the recessive trait? 20

45. In Mendel’s experiments, what percent of the offspring in the first generation carried the recessive trait? A: 100% (All of the plants had the genotype Pp, and “p” is the recessive allele) 20 - Answer

46. Different forms of a characteristic are called ________. 21

47. Different forms of a characteristic are called traits. 21 - Answer

48. What happened to the recessive traits in the second generation of Mendel’s experiments? Include percentages in your answer. 22

49. What happened to the recessive traits in the second generation of Mendel’s experiments? A: They reappeared in 1 out of 4 plants, or 25% of the plants 22 - Answer

50. What is heredity? 23

51. What is heredity? A: Traits passing from parents to offspring 23 - Answer

52. The allele for freckles is (f). Suppose two non- freckled parents have 4 non-freckled children and 1 freckled child. What are the genotypes of the parents? 24

53. A: Since both parents have no freckles, there are only 2 possible combinations: FF or Ff. Both parents have to be heterozygous (Ff) in order to have a child that has shows the recessive trait of freckles. Male Female F = No freckles f = freckles F f F fff Ff 24 - Answer Ff FF

54. A: If either parent is homozygous dominant (FF), all children would show the dominant trait of no freckles. Male Female F = No freckles f = freckles F F F fFf FF 24 – Answer, cont. Ff FF

55. A plant is able to self- pollinate. Does this mean it is a true-breeding plant? 25

56. A: No. Self pollination allowed Mendel to create true- breeding plants, but in his second experiments, he allowed the heterozygous plants to self-pollinate, and purple plants produced both purple and white offspring. 25 - Answer
