Question
Consider the following statements. Â
>1) Genetic engineering aims to introduce an alien gene which could be from a plant, an animal or even a soil bacterium. 2) In India, the Genetic Engineering Appraisal Committee (GEAC) is the apex body that allows for commercial release of GM crops. 3) Approximately 50% of India’s cotton area is under Bt cotton.  Which of the above statements is/are correct?Solution
Conventional plant breeding involves crossing species of the same genus to provide the offspring with the desired traits of both parents. Genetic engineering aims to transcend the genus barrier by introducing an alien gene in the seeds to get the desired effects. The alien gene could be from a plant, an animal or even a soil bacterium. Bt cotton, the only GM crop that is allowed in India, has two alien genes from the soil bacterium Bacillus thuringiensis (Bt) that allows the crop to develop a protein toxic to the common pest pink bollworm. In India, the Genetic Engineering Appraisal Committee (GEAC) is the apex body that allows for commercial release of GM crops. In 2002, the GEAC had allowed the commercial release of Bt cotton. More than 95 per cent of the country’s cotton area has since then come under Bt cotton. Â
