Question

Name 44. 38. Coat color in mice depends upon gene. If C is dominant, the A allele pi epends upon the C gene and the A (broe, IfCis ce depends upon the C gene and the A while aa produces solid black mice. or is albino white, no matter the A/a e mouse coat color genes demonstrate (brown-cre s dominant, the A allele produces agouti wn-gray) mice, while aa produces so In mice, coat color is albino white, genotype. These mouse coat color a. Epistasis b. Pleiotropy c. Continuous variation d. Complementary genes 45. The necessity for more mouse fur stylists. e. 39. In rose plants, pink petaled flowers are dominant to white, and resistance to black spot disease (fungal) is dominant to susceptibility. A rose homozygous for dominant traits is crossed with a plant homozygous for both recessive traits. Pink & resistant F1 progeny are crossed with a tester strain and produce: 82 pink resistant plants, 23 white resistant plants, 17 pink susceptile plants, and 78 white susceptible plants. These data indicate that the genes a. Assort independently b. Are linked, and do not cross-over c. Are linked, and are 10 cM apart d. Are linked, and are 20 cM apart both are 46 e. Are linked, and are 40 cM apart 4 is one form of a gene, while is the precise position of a 40. A(n) a(n) gene on a chromosome. a. Trait; character b. Locus; allele. c. Allele; Locus. d. Character; Trait e. Stonewashed; the Sportswear department.

Explanation / Answer

38. a

44. b oo* AB         type A or type B

45, d X-linked dominant

The trait does not skip generation

Affected males must come from affected mother

46. a Autosomal recessive

same number of males and females are affected

47. c X-linked recessive

48. c X- linked recessive

50. d
