Wikipedia
A breed is a group of domestic animals or plants with a homogeneous appearance, behavior, and other characteristics that distinguish it from other animals of the same species. When bred together, animals of the same breed pass on these uniform traits to their offspring, and this ability—known as "breeding true"—is a definitive requirement for a breed. Plant breeds are more commonly known as cultivars.
