Strategies for Enhancement in Food Production MCQs

Analyze the following statements about global agricultural production and livestock:

I. India and China hold the majority of the global livestock population.
II. Despite high livestock populations, productivity per unit in India and China is low.
III. Traditional animal husbandry practices are completely sufficient to meet the global food demand.
IV. Contribution to world farm produce by India and China combined is 70%.

Select the option with correct statements:

Compare dairy and poultry farm management protocols using the statements below:

I. Both dairy and poultry management require the selection of disease-free and suitable breeds.
II. Proper feed and water are essential only for dairy cattle, whereas poultry birds survive on minimal environmental feeding.
III. Hygiene and healthcare are paramount in poultry management, especially to prevent viral scares like bird flu.
IV. Cleanliness in dairying is vital only for the handler and not for the cows.

Which of these statements are correct?

Read the statements about the genetics of inbreeding:

I. Inbreeding is necessary if we want to evolve a pureline in any animal.
II. Recessive genes exposed by inbreeding are always beneficial and preserved.
III. Inbreeding exposes harmful recessive genes, allowing them to be eliminated by selection.
IV. Inbreeding helps to preserve heterozygosity across generations.

Choose the correct option:

Analyze the ancestral pedigree limits in breeding:

I. Out-crossing involves mating animals of the same breed with no common ancestors on either side up to 4-6 generations.
II. Cross-breeding involves mating superior animals of completely different breeds.
III. Out-crossing is done to combine the traits of two different breeds into a hybrid.
IV. Cross-breeding results in an offspring known as an out-cross.

Which of the statements are correct?

Consider the following statements regarding advanced reproductive technologies:

I. The success rate of crossing mature male and female animals via artificial insemination is always 100%.
II. MOET is used to improve the success rate of successful hybrid production.
III. In MOET, the fertilised eggs are recovered surgically at the 8-32 cell stage.
IV. After non-surgical transfer of embryos to surrogate mothers, the genetic mother is immediately available for superovulation.

Select the correct statements:

Analyse the habitat classifications of the following common food fishes:

I. Catla and Rohu are freshwater fishes commonly eaten in India.
II. Hilsa, Sardines, and Mackerel are common marine fishes.
III. Common carp is a marine species cultivated in coastal estuaries.
IV. Pomfrets belong to freshwater habitats.

Choose the correct option representing correct statements.

Regarding the economic and technical aspects of fisheries, read these statements:

I. Fisheries provision of income is limited to freshwater states and does not benefit coastal states.
II. Aquaculture and pisciculture techniques are used to increase the production of both freshwater and marine organisms.
III. The flourishing fishery industry has led to the Blue Revolution.
IV. Blue Revolution was implemented along the same lines as the Green Revolution.

Select the correct combination.

Evaluate the timeline and basic definitions of plant breeding:

I. Traditional farming yields limited biomass, but better management can increase it indefinitely.
II. Recorded evidence of plant breeding dates back to 9,000–11,000 years ago.
III. All our major modern food crops are derived from domesticated varieties.
IV. Classical plant breeding involves hybridization of pure lines followed by artificial selection.

Identify the correct statements.

Read the statements below regarding the initial steps of plant breeding:

I. Pre-existing genetic variability is often available from wild relatives of the crop.
II. Germplasm collection refers strictly to the collection of only the high-yielding domestic seeds of a crop.
III. Evaluation of germplasm is done to identify plants with a desirable combination of characters.
IV. Purelines are never created during parent selection to preserve heterozygosity.

Choose the correct option.

Which of the following statements are correct regarding cross-hybridization among selected parents?

I. Cross-hybridization is a quick and simple process because pollen grains are automatically accepted by the stigma.
II. Combining high protein quality of one parent with disease resistance of another is an example of cross-hybridization.
III. Usually, almost all crosses (more than 90%) show the desired combination of characters.
IV. Cross-hybridization genetically combines characters from two different parents.

Select the correct option.
