Match List-I with List-II. Choose the correct answer from the options given below.

  1. (a)-(iv), (b)-(iii), (c)-(ii), (d)-(i)
  2. (a)-(iii), (b)-(iv), (c)-(ii), (d)-(i)
  3. (a)-(ii), (b)-(i), (c)-(iv), (d)-(iii)
  4. (a)-(iii), (b)-(iv), (c)-(i), (d)-(ii)

Answer

(3) (a)-(ii), (b)-(i), (c)-(iv), (d)-(iii)

Solution

(a) Fusion of protoplasts of tomato and potato gives the somatic hybrid pomato: (a)-(ii).

(b) Plant tissue culture is based on totipotency — the capacity of a cell or explant to grow into a whole plant: (b)-(i).

(c) Meristem (apical and axillary) is free of virus, so meristem culture gives virus-free plants: (c)-(iv).

(d) Micropropagation produces thousands of genetically identical plants called somaclones: (d)-(iii).

(a)-(ii), (b)-(i), (c)-(iv), (d)-(iii)

Answer: (3)

Which of the following is not a step in Multiple Ovulation Embryo Transfer Technology (MOET)?

  1. Fertilized eggs are transferred to surrogate mothers at 8-32 cell stage
  2. Cow is administered hormone having LH like activity for super ovulation
  3. Cow yields about 6-8 eggs at a time

By which method was a new breed ‘Hisardale’ of sheep formed by using Bikaneri ewes and Merino rams?

  1. Out crossing
  2. Mutational breeding
  3. Inbreeding
  4. Cross breeding
Out of syllabusNEET (UG) 2020
5

Select the incorrect statement.

  1. Inbreeding selects harmful recessive genes that reduce fertility and productivity.
  2. Inbreeding helps in accumulation of superior genes and elimination of undesirable genes.
  3. Inbreeding increases homozygosity.
  4. Inbreeding is essential to evolve purelines in any animal.

Homozygous purelines in cattle can be obtained by :

  1. mating of related individuals of same breed
  2. mating of individuals of different species
  3. mating of individuals of different breed
  4. mating of unrelated individuals of same breed
Out of syllabusNEET 2017

Interspecific hybridisation is the mating of

  1. animals within same breed without having common ancestors
  2. superior males and females of different breeds
  3. more closely related individuals within same breed for 4-6 generations
  4. two different related species

Among the following edible fishes, which one is a marine fish having rich source of omega-3 fatty acids ?

  1. Mangur
  2. Mystus
  3. Mackerel
  4. Mrigala

Outbreeding is an important strategy of animal husbandry because it :

  1. helps in accumulation of superior genes.
  2. is useful in overcoming inbreeding depression.
  3. is useful in producing purelines of animals.
  4. exposes harmful recessive genes that are eliminated by selection.
