What is selective breeding and what is it used for?
Selective breeding, also known as artificial selection, is a process used by humans to develop new organisms with desirable characteristics. Breeders select two parents that have beneficial phenotypic traits to reproduce, yielding offspring with those desired traits.
The advantages of selective breeding include increased profitability and the ability to rid future offspring of disease and disability. The disadvantages include a loss of genetic variety and possible difficulties and discomfort in the animals' lives.

- Selective breeding. Natural selection and selective breeding can both produce changes in animals and plants. Farmers have used selective breeding for centuries to increase milk yield in cattle, produce larger eggs from chickens and obtain more grain from wheat.
- Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.
