Industrial Value Question 2:
Select the incorrect statement regarding inbreeding.
Answer (Detailed Solution Below)
Industrial Value Question 2 Detailed Solution
The correct answer is option 2.
Concept:
- The breeding between animals of the same breed is called inbreeding.
- In inbreeding, more closely related individuals of the same breed are allowed to breed for 4-6 generations.
Explanation:
Let us look at some of the features of inbreeding:
- Here, the superior male and superior female of the same breed are mated in pairs.
- The progeny obtained are evaluated and the ones with superior features are identified. The superior male and female are used for further mating.
Advantages of inbreeding:
- Inbreeding increases the homozygosity (individuals with identical alleles of a gene) of the population.
- Inbreeding exposes harmful recessive genes and they can be eliminated by selection.
- Inbreeding results in a pure line of animals as it is between individuals of the same breed.
- It leads to the accumulation of superior genes/alleles and the elimination of nondesirable genes/alleles.
- As this process involves selection at each stage, it leads to an increase in productivity.
Disadvantages of inbreeding:
- Continued inbreeding between closely related individuals can cause loss of fertility and a reduction in productivity. This is called inbreeding depression.
Way to overcome inbreeding depression:
- This can be overcome by mating superior individuals of the population with unrelated superior individuals of the same breed.
- Such mating between animals of the same breed that do not have common ancestors for up to 4 to 6 generations is called outcrossing.
- It helps in restoring fertility and productivity.
So, the correct answer is option 2.
Industrial Value Question 3:
Consider the following :
1. Algae
2. Fungi
3. Protozoa
Which of the above can be used for the production of Single Cell Protein?
Answer (Detailed Solution Below)
Industrial Value Question 3 Detailed Solution
The correct answer is 1.2 and 3 only.
Key Points
- Single-cell protein refers to the crude, refined or edible protein extracted from pure microbial cultures, dead, or dried cell biomass.
- They can be used as a protein supplement for both humans and animals.
- Microorganisms like algae, fungi, yeast, and bacteria have very high protein content in their biomass.
- Microorganisms, such as algae, fungi, protozoa, and bacteria are used for the production of SCP. Hence option 4 is correct.
- These microbes can be grown using inexpensive substrates like agricultural waste viz. wood shavings, sawdust, corn cobs, etc., and even human and animal waste.
- The microorganisms utilize the carbon and nitrogen present in these materials and convert them into high-quality proteins which can be used as a supplement in both human and animal feed.
- The single-cell proteins can be readily used as fodder for achieving the fattening of calves, and pigs, in breeding fish, and even in Animal Husbandry – Poultry and Cattle Farming.
- Single Cell Protein (SCP) offers an unconventional but plausible solution to this problem of protein deficiency being faced by the entire humanity.

- The bright or dark green patches found in wet regions are algae, the non-flowering plants like species containing chlorophyll yet distinct from floras ranging from micro to macro sizes.
- The processing of these microorganisms diversifies the scope in the nutrition industry, bioplastics, pharmaceuticals, special chemicals manufacture, organic fertilizer, and the flourishing biofuel industry.
- The list of fuels that can be derived from algae includes:
- Biodiesel,
- Butanol,
- Gasoline,
- Methane,
- Ethanol,
- Vegetable Oil,
- Jet Fuel.
- The distinctive properties of algae such as:
- CO2 absorbance for growth helps in the reduction of the greenhouse effect.
- They do not require a large area for development compared to other food crops.
- They can adjust to brine water.
- Their lipid content is found high.
- The lipids in algae can be converted to biodiesel by the generalized method used for the conversion of vegetable oil into biodiesel.
- There are two different types of algae that can be produced to make biofuels: macroalgae and microalgae.
- Macroalgae are large, multi-cellular organisms that are measured in inches and grow in ponds.
- Microalgae are micro, unicellular organisms that are measured in micrometres and grow in suspension within a body of water.
So, the correct answer is option 4.
Industrial Value Question 5:
Domestication of silk worm is called:
Answer (Detailed Solution Below)
Industrial Value Question 5 Detailed Solution
Key Points
- Sericulture, also known as silk farming, is the cultivation of silkworms to produce silk.
- Typical process:
- Silk Moth Egg Stage: The process begins with the breeding of silk moths. The eggs laid by the female moth are carefully collected and incubated.
- Larva Stage: After being incubated, the eggs hatch into larvae, which are also known as silkworms. These larvae are fed with mulberry leaves, upon which they grow and develop.
- Spinning Cocoon: After sufficient growth that usually lasts for 25-30 days, the silkworms start spinning cocoons using their salivary glands, which produce the silk. The silkworm rotates its body in a figure-8 movement about 300,000 times, producing a filament of about 900 meters long.
- Collection of Cocoons: Once the cocoon is fully formed, it is carefully detached and collected before the silk moth starts secreting a fluid to break down the silk and emerge. This is crucial because the moth can damage the continuity of the silk filament.
- Silk Extraction (Reeling) and Spinning: In this stage, collected cocoons are boiled to soften the sericin, a protective gum holding the silk fibers together. Subsequently, the ends of the filament are located, and the silk is unwound onto reels in a process called "reeling". The silk fibers are then twisted together to form a stronger thread, in a process called "throwing", and are finally spun into silk threads or yarns.
- Fabric Production: The silk threads or yarns are then woven into silk fabrics or used in the production of silk products.
Additional Information
- The most common silk moth used in commercial production is the species Bombyx mori, whose preferred food, as stated above, is the leaves of the mulberry tree.

- Domestic silk moths are largely dependent on humans for the reproduction, therefore selective breeding helps in the production of good quality of silk.
- It is the primary moth and is one of the most economical insects for the production of silk.
Industrial Value Question 7:
By which method was a new breed ‘Hisardale’ of sheep formed by using Bikaneri ewes and Marino rams?
Answer (Detailed Solution Below)
Industrial Value Question 7 Detailed Solution
Concept:
- The breeding of animals is an important feature of animal husbandry.
- It is performed to increase the yield of animals and also, to improve the desired qualities.
Important Points
There are different ways to breed animals. Let us see a few of them:
- Crossbreeding -
- In this superior male of one breed mates with a superior female of the other breed.
- This procedure enables superior qualities of both breeds to be combined; mainly for commercial purposes.
- Ex. Hisardale is the breed of sheep in Punjab. It is obtained by cross-breeding between Bikaneri ewes and Marino rams.
- Inbreeding -
- In this procedure superior male mates with a superior female of the same breed.
- It is breeding between closely related individuals within the same breed for 4 - 6 generations.
- Ex. a superior female of the breed can be a cow or buffalo that produces more milk per lactation while a superior male could be a bull that gives rise to superior progeny.
- Outcrossing -
- It is the procedure of mating between animals of the same breed but without any common ancestors on either side for 4 - 6 generations.
- It is the best breeding method for animals with below-average productivity in milk, meat, etc.
Additional Information
Let us see one of the breeding methods in plants:
- Mutational breeding -
- The process by which genetic variations in the base sequence of the DNA create a new trait/character different from parents is called a mutation.
- Mutations can be induced in plants with the help of chemicals or using gamma radiation.
- In mutational breeding, the plants produced with desirable characters are used for breeding.
- Ex. mung bean produced by mutational breeding has resistance to yellow mosaic virus.
So, the correct answer is option 1.
Industrial Value Question 8:
Honey is produced by the honeybee. So, the honeybee is a ______.
Answer (Detailed Solution Below)
Industrial Value Question 8 Detailed Solution
The correct answer is primary consumer.
Key Points
- Honeybees collect nectar from flowers, which makes them primary consumers as they directly feed on producers (plants).
- Primary consumers are organisms that consume producers (plants) for energy.
- In the food chain, primary consumers are typically herbivores or omnivores.
- Honeybees play a crucial role in pollination, which supports the growth of plants and the ecosystem.
Additional Information
- Producers: Organisms that produce their own food using sunlight, water, and carbon dioxide (e.g., plants, algae).
- Primary Consumers: Organisms that feed directly on producers (e.g., herbivores like cows, and insects like honeybees).
- Secondary Consumers: Organisms that consume primary consumers (e.g., carnivores like lions, and omnivores like humans).
- Decomposers: Organisms that break down dead or decaying organisms, recycling nutrients back into the ecosystem (e.g., fungi, bacteria).
- Honeybees contribute to biodiversity by aiding in plant reproduction through the process of pollination.
Industrial Value Question 9:
Silk is obtained from which type of organism?
Answer (Detailed Solution Below)
Industrial Value Question 9 Detailed Solution
The correct answer is Moth.
Key Points
- Bombyx Mori is the type of silk moth, that is domesticated for the production of silk.
- Domestic silk moths are largely dependent on humans for the reproduction, therefore selective breeding helps in the production of good quality of silk.
- It is the primary moth and is one of the most economical insects for the production of silk.
Industrial Value Question 10:
Yeast can be used in making which of the following?
1. Winemaking
2. Spirits production
3. baking
4. Biomass production
Select the correct answer using the code given below:
Answer (Detailed Solution Below)
Industrial Value Question 10 Detailed Solution
The correct answer is 1, 2, 3, and 4.
Key Points
- Yeasts represent a very diverse group of microorganisms, and even strains that are classified as the same species often show a high level of genetic divergence.
- Yeasts biodiversity is closely related to their applicability.
- The Biotechnological importance of yeast is almost immeasurable.
- Yeasts have a wide range of applications mainly in the food industry (winemaking, brewing, distilled spirits production, and baking) and in biomass production (single-cell protein [SCP]). Hence option 4 is the correct answer.
- More recently, yeast has also been used in the biofuel industry and for the production of heterologous compounds.
- Obviously, their main application arises from the metabolic capacity to carry out the transformation of sugars into ethyl alcohol and carbon dioxide under anaerobic conditions.
- Moreover, a large number of secondary flavor compounds are created which implies organoleptic attributes of particular food products.
- However, it would be misguided to trivialize their metabolic capacities only to fermentative activity.
- The main factors influencing yeast metabolism are oxygen availability and the type of carbon source.
- In food industry, Saccharomyces cerevisiae is the genus of yeast most frequently used, whereas Candida, Endomycopsis, and Kluyveromyces are crucial for SCP production.
So, the correct answer is option 4.
