Which of the following is not an objective of Biofortification of crops?

1. Improve micronutrient and mineral content
2. Improve protein content

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

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

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

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.

A protoplast is a cell -

1. undergoing division
2. without plasma membrane
3. without nucleus
4. without cell wall
