See Breed (song) for the song of the same name by Nirvana.

A breed has no close analogy for domesticated plants. An important difference is that plants are commonly propagated by striking or grafting cuttings: there is no corresponding technique for animals. Cloning may change this if it becomes more available.

A breed should also be distinguished from a strain, which is simply the descendants of a single significant individual, and which in domesticated animals is also known as a bloodline. A strain may not remain entirely within a breed, nor is a breed necessarily composed of a single strain.
