Answer the Quesions with True / False
33. When two double heterozygous are mated, four different
phenotypes are produced in a ratio 9:3::3:1
34. When two double heterozygous are mated 9 different
genotypes are produced
35. An intense mating between two triple heterozygous will
produce a phenotypic ration of 27:9:9:9:3:3:3:1
36. 27 different genotypes are produced and nine different
phenotypes are observed when two triple heterozygous are
mated
37. In a trihybrid inheritance, the perfect population size is
64
38. The number of phenotypes produced in the f2 when five
gene
pairs are mated is 32
39. All traits of economic importance in farm animals are
under
the influence of polygenes
40. In complete dominance, the heterozygous and the the
homozygous dominants are distinguishable
41. In over dominance, the heterozygous is superior to both
homozygous
42. The naked neck gene is an example of incomplete dominance
because the homozygous dominant and the heterozygous
individuals are indistinguishable
43. Some genes are associated with sex because they occur on
the sex chromosomes. Such genes are called sex influence
genes
44. Sex linked genes do not occur on the sex chromosomes but
are rather influenced by sex hormones
45. The epistatic gene ,recessive white is an allele of the
epistatic
gene, dominant gene
46. Traits that show continuous variation are known as
qualitative
traits
47. The environment has little or no effects on quantitative
traits
48. Phenotypic variations in quantitative traits is the results
of
genetic variation variation, interactions of heredity and the
environment
49. In animal breeding programs, the average performance of
selected parents is always lower than that of the population
from
which they were selected
50. The chicken can have a colored plumage only when the two
epistatic genes, dominant and recessive white exist in the
genotypes iiCC or iiCc
51. The genotype P-R in chickens produces a comb type called
walnut comb
52. Genes that are responsible for quantitative traits do not
follow
the mendelian inheritance
53. In poultry, the female is homogenetic and the male is
heterogenetic
54. Epistasis could be used to explain the rise in performance
in
hybrid individuals above the average of their parents
55. In additive gene action, the genotype reflects the
phenotype
56. Feed conversion ratio is a trait that shows discrete
variation
57. In quantitative traits, the offspring inherits 50% of
superiority
of genes above the average of the population
58. Bodyweight, egg numbers and polydactyl are all examples
of
quantitative traits
59. Animal breeding deals with application of genetic
principles
and statistics for the improvement of farm animals
60. The gene mf masks the expression of the gene F which is
responsible for the frizzling
33. When two double heterozygous are mated, four different
phenotypes are produced in a ratio 9:3::3:1
