  • A 1856-1863
  • B 1840-1850
  • C 1857-1869
  • D 1870-1877

Question - 4

Among the following characters, which one was not considered by Mendel in his experiments of pea?

  • A Stem - Tall or Dwarf
  • B Trichomes - Glandular or non-glandur
  • C Seed - Green or Yellow
  • D Pod - Inflated or constricted

Question - 5

A tall true breeding garden pea plant is crossed with a dwarf true breeding garden pea plant. When the Fl plants were selfed, the resulting genotype were in the ratio of :

  • A 1:2:1:: Tall heterozygous: Tall homozygous: Dwarf
  • B 3:1:: Tall:Dwarf
  • C 3:1:: Dwarf: Tall
  • D 1:2:1: Tall homozygous: Tall heterozygous: Dwarf

Question - 6

Match the terms in Column I with their description in column II and choose the correct option

Column I Column II
(A) Dominance (i) Many genes govern a single character
(B) Co-dominance (ii) In a heterozygous organisms only one allele expresses itself
(C) Pleiotropy (iii) In a heterozygous organism both alleles express themselves fully
(D) Polygenic inheritance (iv) A single gene influences many characters
  • A A B C D (ii) (iii) (iv) (i)
  • B A B C D (iv) (i) (ii) (iii)
  • C A B C D (iv) (iii) (i) (ii)
  • D A B C D (ii) (i) (iv) (iii)

Question - 7

In a test cross involving Fl dihybrid flies, more parental type offspring were produced than the recombinant type offspring. This indicates:

  • A Chromosomes failed to separate during meiosis
  • B The two genes are linked and present on the same chromosome
  • C Both of the characters are controlled by more than one gene
  • D The two genes are located in two different chromosomes

Question - 8

The fruit colour is squash is an example of:

  • A Recessive epistasis
  • B Dominant epistasis
  • C Complementary epistasis
  • D Inhibitory genes

Question - 9

A test cross is carried out to:

  • A  Determine whether two species or verities will breed successfully
  • B Predict whether two trails are linked   
  • C Assess the number of alleles of a gene
  • D Determine the genotype of F2 plant

Question - 10

F2 generation in a Mendelian cross showed that both genotypic and phenotypic ratios are same as 1: 2: 1. It represents a case of:

  • A Monohybrid cross with complete dominance
  • B Monohybrid cross with incomplete dominance
  • C Codominance
  • D Dihybrid cross
