#1. .Select the incorrect statement.

Inbreeding increases homozygosity

Inbreeding is essential to evolve purelines in any animal.

Inbreeding selects harmful recessive genes that reduce fertility and productivity

Inbreeding helps in accumulation of superior genes and elimination of undesirable genes

Inbreeding exposes harmful recessive genes that are eliminated by selection. It also helps in accumulation of superior genes and elimination of less desirable genes. selection at each step, increase the productivity of inbred population. Close and continued inbreeding usually reduces fertility and even productivity.

#2. Homozygous purelines in cattle can be obtained by

Mating of related individuals of same breed

Mating of unrelated individuals of same breed

Mating of individuals of different breed

Mating of individuals of different species

Inbreeding results in increase in the homozygosity. Therefore, mating of the related individuals of same breed will increase homozygosity.

#3. Outbreeding is an important strategy of animal husbandry because it

Exposes harmful recessive genes that are eliminated by selection.

Helps in accumulation of superior genes.

Is useful in producing purelines of animals.

Is useful in overcoming inbreeding depression

A single outcross (a type of outbreeding) is useful in overcoming inbreeding depression.

#4. Which one of the following is viral disease of poultry?

Pasteurellosis

Salmonellosis

Coryza

New Castle disease

New Castle disease– Caused by New Castle disease virus (NDV).

Coryza-Bacterial disease: Haemophilus paragallinarum.

Pasteurellosis– Bacterial disease: Pasteurella

Salmonellosis– Bacterial disease: Salmonella

#5. In cloning of cattle a fertilized egg is taken out of the mother’s womb and

From this upto eight identical twins can be produced

The egg is divided into four pairs of cells which are implanted into the womb of others cows

In the eight cell stage, cells are separated and cultured until small embryos are formed which are implanted into the womb of other cows

In the eight cell stage the individual cells are separated under electrical field for further development in culture media

#6. The causative agent of mad-cow disease is a

Bacterium

Prion

Worm

Virus

#7. The term aquaculture means

Inland fisheries

Culture fishery only

Marine fisheries

Both (1) & (3)

Aquaculture involves production of all useful aquatic plants and animals. It involves both inland and marine fisheries.

#8. Mating of more closely related individuals within the same breed for 4-6 generation is

Outbreeding

Interspecific breeding

Inbreeding

Cross breeding

Interspecific breeding– Mating of different species.

Cross-breeding– Mating of different breeds of same species.

#9. Inland fisheries involve

Culturing fish in ponds

Culturing endogenous breed of fish in deep sea and coastal areas

Culturing exotic breed of fish in estuaries

Culturing any breed of fish in marine water

Inland fisheries include fresh water fisheries.

Deep sea and coastal areas, Estuaries, Marine water, all are marine water sources

#10. Inbreeding depression occurs due to

Continued out crossing within the small local population

Continued cross breeding within the small local population

Continued inbreeding within the small local population

Interspecific hybridisation

Continued inbreeding reduces fertility and even productivity.

#11. Which one is wrongly matched?

Apiculture– Honey bee only

Aquaculture– Fish only

Sericulture– Silk moth only

Poultry - Ducks

Aquaculture involves production of all aquatic plants and animals.

#12. Three carp fishes, Catla, Labeo and Cirrhina, can be grown together in the same pond more economically, as they have

Positive interactions

Commensalism

Symbiosis

No competition for food

As these carps have different feeding habits.

#13. Out-crossing, cross-breeding and interspecific hybridization are included in

Inbreeding

Out-breeding

Inbreeding depression

Farm management

#14. In polyculture two or more than two species of fishes are grown together in the same water body based on their

Size

Feeding habits

Reproductive habit

Mode of respiration

Different fishes can be cultured together as they have different feeding habits so there will be no competition for food.

#15. Mark the viral disease in cattle

Cattle plague

Anthrax

Foot and mouth disease

Both (1) & (3)

#16. White revolution is associated with enhancement of

Fish production

Egg production

Milk production

Wheat and rice production

Fish production – Blue revolution

Wheat and rice production – Green revolution.

#17. Which among the following is the real product of the honey bee?

Honey

Propolis

Pollen

Bee wax

It is secreted by abdominal wax glands of the worker bees.

Honey– is made by using nectar of flowers.

#18. High milk yielding varieties of cows are obtained by

Use of surrogate mothers

Super ovulation

Artificial insemination

All of these

They are part of MOET (Multiple ovulation and embryo transfer)

#19. Choose the species of honey bee that is most commonly found in Indian subcontinent

Apis mellifera

Apis dorsata

Apis florea

Apis indica

Apis indica– Most common Indian species of honeybee.

Apis florea– Little bee or smallest honeybee.

Apis dorsata– The giant bee or rock bee. It is a defensive bee and it is not domesticated.

#20. Culturing meristem of banana, sugarcane and potato is primarily significant to produce

Somatic hybrids

Virus free plants

Specific meristematic tissue

Hybrid vigour

Meristem of plants are viral free in nature.

#21. Somaclones are obtained by

Tissue culture

Plant breeding

Genetic engineering

Irradiation

Somaclones are obtained by tissue culture. These are the group of plants that are genetically identical to parent plant.

#22. Capacity of a plant cell to give rise to whole plant body is known as

Reproduction

Budding

Totipotency

Regeneration

#23. Prokaryote that is considered as source of SCP is

Rhizobium

Frankia

Streptococcus

Spirulina

Spirulina is prokaryotic i.e. the source of protein (SCP).

#24. Atlas-66 is

Maize variety

Wheat variety with high protein content

Brassica variety with resistance against aphids

Cowpea variety with resistance against bacterial blight

Atlas-66 is wheat variety with high protein content.

#25. Plant variety himgiri is resistant to

White rust
