Which of the following is not a benefit of genetically modified plants/crops?

Lower yield

The correct answer is Option (3) → Lower yield

Plants, bacteria, fungi and animals whose genes have been altered by manipulation are called Genetically Modified Organisms (GMO). GM plants have been useful in many ways. Genetic modification has:

(i) made crops more tolerant to abiotic stresses (cold, drought, salt, heat).

(ii) reduced reliance on chemical pesticides (pest-resistant crops).

(iii) helped to reduce post harvest losses.

(iv) increased efficiency of mineral usage by plants (this prevents early exhaustion of fertility of soil).

(v) enhanced nutritional value of food, e.g., golden rice, i.e., Vitamin ‘A’ enriched rice.

 "Lower yield" is not a benefit of genetically modified (GM) plants or crops. In fact, GM crops are often developed to increase yield by making them more resistant to pests, diseases, and abiotic stresses (such as drought, salinity, and extreme temperatures). Other benefits of GM crops include pest resistance and enhanced nutritional value, both of which contribute to better crop productivity and quality.
