Statement I: Many crops are incorporated with foreign genes to make them tolerant to abiotic stresses.

Statement II : Genomes of many plants are manipulated or altered by combining them with other genes to get desired traits.

Both statements I and II are correct .

The correct answer is option (3) - Both statements I and II are correct .

Statement I: Many crops are incorporated with foreign genes to make them tolerant to abiotic stresses.

Explanation: Abiotic stresses are environmental factors such as drought, extreme temperatures, salinity, and metal toxicity that can negatively affect plant growth and development. To improve the resilience of crops under such adverse conditions, scientists use genetic engineering techniques to introduce foreign genes into crop plants. These foreign genes can come from other plant species or organisms and are chosen for their ability to confer tolerance to specific abiotic stresses. The process of introducing foreign genes into a plant's genome is known as genetic modification or genetic engineering. By incorporating these foreign genes, crop plants can withstand harsh environmental conditions better and show improved growth and yield under stress conditions.

Statement II: Genomes of many plants are manipulated or altered by combining them with other genes to get desired traits.

Explanation: Genetic manipulation or genome alteration is a process where scientists modify the DNA of plants to introduce specific traits or characteristics. This is achieved by combining the plant's own genes with genes from other organisms, which may include other plant species, bacteria, or even animals. The goal is to introduce desirable traits into the plant, such as resistance to diseases or pests, improved nutritional content, enhanced yield, or better adaptation to specific environmental conditions.

The process of genetic manipulation involves identifying and isolating the genes responsible for the desired traits, introducing these genes into the plant's genome, and ensuring that they are expressed correctly.

Both Statement I and Statement II refer to genetic engineering techniques used to improve crop plants. By incorporating foreign genes, scientists can enhance the crops' ability to tolerate abiotic stresses and introduce desirable traits into plants, making them more productive, nutritious, and resilient in challenging environments. However, it's essential to carefully consider the environmental and ethical implications of genetic manipulation and ensure proper safety assessments before introducing genetically modified crops into the agricultural landscape.
