breed

All dogs, from the giant Great Dane to the tiny Chihuahua, belong to the same species: Canis familiaris. Within that single species, there are many breeds or types. Humans produced these breeds over many generations by mating individuals with certain traits. This process is
called breeding. Along with many animal species, people have also bred plants like tomatoes and bananas to create breeds with desirable traits.

Definition: A group of individuals within a species that exhibit particular traits as a result of artificial (human) selection.
Process: Over generations, humans mate animals or plants with desirable traits, which are passed down to offspring.
History: First began thousands of years ago when humans started farming and herding.
