What is genetic engineering?

Explanation:
Genetic engineering is the intentional modification of an organism’s DNA in the lab to create desired traits by adding, removing, or changing specific genes. This direct alteration of the genetic material distinguishes it from traditional breeding, which changes traits by selecting and mating animals over generations rather than editing genes themselves. In livestock, this can enable traits like disease resistance or improved growth through precise genetic changes. The other activities—breeding programs, nutritional supplementation, and health management—rely on selecting, feeding, or caring for animals without directly altering their DNA.
