1. Question 1 (NEET 2018)

   NEET 2018EasyCryopreservation

   Pollen grains can be stored for several years in liquid nitrogen having a temperature of:

   1. AOption A: -120°C
   2. BOption B: -80°C
   3. COption C: -160°C
   4. DOption D: -196°C

   Show answer & explanationHide answer & explanation

   Correct answer: (D) -196°C

   Explanation

   Pollen grains are preserved by cryopreservation in liquid nitrogen at -196°C. Hence, option (D) is correct.

2. Question 2 (AIPMT 2015)

   AIPMT 2015EasyAnimal Breeding

   Outbreeding is an important strategy of animal husbandry because it:

   1. AOption A: Exposes harmful recessive genes that are eliminated by selection
   2. BOption B: Helps in accumulation of superior genes
   3. COption C: Is useful in producing purelines of animals
   4. DOption D: Is useful in overcoming inbreeding depression

   Show answer & explanationHide answer & explanation

   Correct answer: (D) Is useful in overcoming inbreeding depression

   Explanation

   Outbreeding introduces genetic variation and helps overcome inbreeding depression by reducing the expression of harmful recessive alleles.

3. Question 3 (NEET 2013)

   NEET 2013MediumPlant Breeding

   In plant breeding programmes, the entire collection of plants/seeds having all the diverse alleles for all genes in a given crop is called

   1. AOption A: Selection of superior recombinants
   2. BOption B: Cross-hybridisation among selected parents
   3. COption C: Evaluation and selection of parents
   4. DOption D: Germplasm collection

   Show answer & explanationHide answer & explanation

   Correct answer: (D) Germplasm collection

   Explanation

   The total collection of genetic variability of a crop is called germplasm collection.

4. Question 4 (AIPMT 2012)

   AIPMT 2012HardSingle Cell Protein and Biofortification

   Consider the following four statements (a-d) and select the option which includes all the correct ones only: (a) Single cell protein can produce large quantities of food rich in protein, minerals, vitamins etc. (b) Body weight-wise the microorganism Methylophilus methylotrophus may be able to produce several times more proteins than the cows per day (c) Common button mushrooms are very rich source of vitamin C (d) A rice variety has been developed which is very rich in calcium

   1. AOption A: Statements (a), (c) and (d)
   2. BOption B: Statements (b), (c) and (d)
   3. COption C: Statements (a), (b)
   4. DOption D: Statements (c), (d)

   Show answer & explanationHide answer & explanation

   Correct answer: (C) Statements (a), (b)

   Explanation

   Statements (a) and (b) are correct. Statement (c) is incorrect because mushrooms are not especially rich in vitamin C. Statement (d) is incorrect because the famous biofortified rice variety is rich in vitamin A (Golden Rice), not calcium. Therefore, option (C) is correct.

5. Question 5 (AIPMT 2012)

   AIPMT 2012EasyGreen Revolution

   Green revolution in India occurred during:

   1. AOption A: 1970’s
   2. BOption B: 1980’s
   3. COption C: 1950’s
   4. DOption D: 1960’s

   Show answer & explanationHide answer & explanation

   Correct answer: (D) 1960’s

   Explanation

   The Green Revolution in India began during the 1960s with the introduction of high yielding varieties of wheat and rice. Therefore, option (D) is correct.

6. Question 6 (AIPMT 2011)

   AIPMT 2011MediumOrganic Farming

   Consider the following statements (A-D) about organic farming: (A) Utilises genetically modified crops like Bt cotton (B) Uses only naturally produced inputs like compost (C) Does not use pesticides and urea (D) Produces vegetables rich in vitamins and minerals Which of the above statements are correct?

   1. AOption A: (B), (C) and (D)
   2. BOption B: (C) and (D) only
   3. COption C: (B) and (C) only
   4. DOption D: (A) and (B) only

   Show answer & explanationHide answer & explanation

   Correct answer: (C) (B) and (C) only

   Explanation

   Organic farming uses natural inputs and avoids synthetic pesticides and fertilisers like urea. It does not utilise GM crops.

7. Question 7 (AIPMT 2006)

   AIPMT 2006EasyHybrid Vigour (Heterosis)

   In maize, hybrid vigour is exploited by:

   1. AOption A: Bombarding the protoplast with DNA
   2. BOption B: Crossing of two inbred parental lines
   3. COption C: Harvesting seeds from the most productive plants
   4. DOption D: Inducing mutations

   Show answer & explanationHide answer & explanation

   Correct answer: (B) Crossing of two inbred parental lines

   Explanation

   Hybrid vigour or heterosis in maize is obtained by crossing two genetically pure inbred parental lines, producing a highly vigorous F₁ hybrid. Hence option (B) is correct.
