Genetic resistance refers to the ability of an organism to resist or tolerate the effects of a pathogen, harmful substance, or environmental stress through genetic mechanisms. This trait is often inherited and passed down from one generation to the next. In the context of agriculture, genetic resistance is a valuable trait that can help crops withstand diseases, pests, and other environmental challenges without the need for chemical interventions. Researchers study genetic resistance to develop new crop varieties with improved resilience and productivity. In the medical field, genetic resistance plays a crucial role in understanding and combating infectious diseases, cancer, and other illnesses. Overall, genetic resistance research aims to enhance the natural resilience of organisms through genetic manipulation and selection processes.
