Question

The most common trait that was improved in commercialized crops was
A. Insect resistance
B. Drought resistant
C. Nutritional quality
D. Productivity

Answer 1

Hint: For the commercial crop farmers should have good productivity, the profit can be achieved only when the crop cultivated has sufficient weight in it, and gets more money.

Complete answer: 1. Insects are one of the major problems for the farmers which continuously decreases the amount of the crop even after harvesting the crop.
2. In commercial crops the total amount of crop determines the amount of profit to the farmer, if insects attack the crop then there is no use of that crop cultivation.
3. Insects damage the crop very badly but biotechnology and genetic engineering can help very much in this and can protect the farmers from a big loss with the help of this a new insect resist gene can be added to the crop which resists the crop from the damage of the insect and a new trait gets evolved in the crop which helps in increasing the productivity and profit of the commercial crop.
So we can say that the insect resistance trait can be improved for commercial crops.

So, the correct answer is “Option A”.

Note: Drought is not a major problem in India as most regions of India get adequate rainfall during the rainy season also have good irrigation systems in India.
2. Nutritional value does not matter for commercial crops as commercial crops are mainly used in the industry not in food products and not for the purpose of improving the nutritional value of the food.
