II. The combined contribution of India and China to the world farm produce is only 25 per cent.
III. The productivity per unit of livestock in India and China is extremely high compared to the rest of the world.

Choose the correct statement(s):

Read the following statements about dairy farm management and breed selection:

I. Milk yield is primarily dependent on the quality of breeds in the farm.
II. Breeding should focus solely on high-yielding potential, irrespective of local climatic adaptability.
III. Resistance to diseases is a crucial selection criterion for choosing dairy cattle breeds.
IV. Mechanisation in milking, storage, and transport increases the risk of direct contact of the produce with the handler.

Identify the correct combination of statements:

Identify which of the following statements are correct regarding the scientific management of dairy farms:

I. Fodder feeding of cattle should emphasize both quality and quantity.
II. Regular visits by a veterinary doctor are optional and only required when an animal shows active symptoms of disease.
III. Stringent cleanliness of both the cattle and the handlers is essential during milking, storage, and transport.
IV. Mechanised processes in modern dairies increase human handling of dairy products.

Choose the correct option:

Consider the following statements regarding poultry farming:

I. Poultry typically includes chicken and ducks, and sometimes turkey and geese.
II. Poultry is always restricted to refer only to the meat of domesticated birds.
III. Proper and safe farm conditions, feed, water, and hygiene are the core components of poultry management.
IV. Bird flu virus is a bacterial pathogen that severely affects poultry farms and drastically impacts consumption.

Which of the statements given above are correct?

To be classified as a distinct breed, a group of animals must satisfy which of the following conditions?

I. They must be related by descent.
II. They must have similar general appearance and configuration.
III. They must be similar in features and size.
IV. They must belong to completely different species that cannot interbreed.

Select the option representing the correct statements:

Based on the principles of animal breeding, analyze the statements below:

I. Inbreeding refers to the mating of closely related individuals within the same breed for 4–6 generations.
II. Outbreeding involves crosses between animals of different breeds or different species, but never within the same breed.
III. Superior cows or buffaloes are those that produce more milk per lactation.
IV. A superior bull is one that gives rise to superior progeny compared to other males.

Which of the statements are correct?

Consider the following statements regarding the genetic outcomes of inbreeding:

I. Inbreeding decreases homozygosity and helps in creating heterozygous lines.
II. The strategy for developing purelines in cattle is similar to the purelines developed by Mendel in peas.
III. Close inbreeding exposes harmful dominant genes that are then eliminated by selection.
IV. Inbreeding helps in the accumulation of superior genes and elimination of less desirable genes.

Choose the correct option:

Regarding close and continued inbreeding in animal populations, evaluate these statements:

I. Continued close inbreeding usually leads to an increase in fertility and productivity.
II. Inbreeding depression is a major problem associated with close inbreeding.
III. Inbreeding depression can be overcome by mating selected animals with unrelated superior animals of the same breed.
IV. Mating with unrelated animals of the same breed usually restores fertility and yield.

Which of the above statements are correct?

Out-breeding is a broad classification of animal breeding. Read the following statements:

I. Out-crossing is the mating of animals of different breeds having common ancestors.
II. Cross-breeding is the mating of superior males of one breed with superior females of another breed.
III. Interspecific hybridisation is the mating of male and female animals of two different related species.

Choose the correct statements:

Which of the following statements are correct about out-crossing?

I. The offspring of an out-crossing mating is known as an out-cross.
II. It is the best breeding method for animals that are above average in productivity.
III. A single out-cross often helps to overcome inbreeding depression.
IV. It involves mating animals of the same breed with common ancestors up to 6 generations.
