Genetic improvement refers to the process of enhancing the traits of organisms, such as plants and animals, through selective breeding or genetic engineering. This can lead to better yields, disease resistance, and improved quality. For example, farmers may choose to breed crops that produce more fruit or are more resilient to pests. In addition to traditional breeding methods, modern techniques like CRISPR allow scientists to make precise changes to an organism's DNA. This can accelerate the development of desirable traits, making it possible to create varieties of livestock or plants that thrive in changing environmental conditions.
