The agricultural practice of breeding and raising livestock is called:
1. | Domestication | 2. | Breeding |
3. | Animal husbandry | 4. | Bio-fortification |
A group of animals related by descent and similar in most characteristics like general appearance, features, size, configuration, etc., are said to belong to a:
1. | Variety | 2. | Species |
3. | Strain | 4. | Breed |
Which of the following is not an advantage of artificial insemination in cattle?
1. | Increased efficiency of bull usage |
2. | Increased genetic variability in the population |
3. | Increased potential for genetic selection |
4. | Reduced disease transmission |
The purposeful manipulation of plant species in order to create desired plant types that are better suited for cultivation, give better yields, and are disease resistant is called:
1. | Breeding | 2. | Genetic farming |
3. | Phytoremediation | 4. | r DNA technology |
A pure line plant:
1. | is defined as having only recessive alleles for the traits at all loci |
2. | breeds true and preserves the trait for many generations |
3. | is not susceptible to any diseases and is used as a parent in plant breeding experiments |
4. | can be produced by inbreeding amongst the endemic varieties only |
The sobriquet ‘Father of Green Revolution’ is used for:
1. | Norman Borlaug | 2. | M. S. Swaminathan |
3. | Gordon Conway | 4. | Elvin Stakman |
Hidden hunger is accurately described as:
1. protein undernutrition
2. calorie undernutrition
3. vitamins and minerals undernutrition
4. PEM
Plant tissue culture is based on:
1. | cellular totipotency | 2. | indeterminate growth |
3. | phenotypic plasticity | 4. | secondary growth |
Consider the given two statements:
I: | Somatic hybridization and cybridization have great potential for plant improvement. |
II: | Somatic hybridization through protoplast fusion provides the ability to combine parent genes in higher plants to overcome sexual incompatibility among plant species or genera. |
1. Both I and II are correct and II explains I
2. Both I and II are correct but II does not explain I
3. I is correct but II is incorrect
4. Both I and II are incorrect
Consider the following two statements:
I: | In spite of having more than 70 percent of the world's livestock population, the contribution of India and China to the world's farm produce is only 25 percent. |
II: | The productivity per unit of cattle in these countries is very low. |
1. Both I and II are true and II explains I
2. Both I and II are true but II does not explain I
3. I is true but II is false
4. Both statements are not true
