Cross-breed is a term used to describe an animal that is the result of breeding two different breeds or species. The antonyms for cross-breed would be purebred, unmixed, or pedigreed. A purebred animal is one that has ancestors of the same breed for many generations. Unmixed means that no other breed or species has been introduced to the animal's genealogy. Pedigreed animals are those that have an official record of their ancestry, showing that they come from a long line of purebred animals. While cross-breeding can often result in unique and desirable traits, breeding within a specific breed or species can ensure consistency and predictability in traits and characteristics.
