What is the result of selective breeding?

Selective breeding is a process used to enhance specific desirable traits in an organism by intentionally mating individuals that exhibit those traits. The goal is to produce offspring that consistently display the preferred characteristics, such as increased yield, disease resistance, or better nutritional quality in crops and livestock. This method relies on the principles of inheritance and genetics, allowing breeders to influence the traits passed to the next generation.

In contrast, while selective breeding can lead to a certain level of genetic diversity, its primary aim is to concentrate favorable traits rather than increase genetic variability. Random mutations may occur, but they are not a direct result of selective breeding, as this process seeks to control breeding outcomes rather than allowing random genetic changes. Finally, while selective breeding can indirectly contribute to improved soil fertility through healthier and more productive plants, improved soil fertility is not a direct outcome of the breeding itself. The focus rests firmly on enhancing specific traits, making the offspring more desirable according to human-defined standards.
