Translation guide
The English word "crossbreed" can be a verb (to produce offspring by mating different breeds or species) or a noun (the resulting offspring). This guide covers both uses, with natural Japanese equivalents.
To deliberately mate two different breeds, varieties, or species to produce offspring with desired traits.
The most common and general verb for crossbreeding, used for both animals and plants. Neutral register.

They are crossbreeding a new breed of dog.
The offspring resulting from crossbreeding, often called a hybrid or cross.
交配種 (kōhaishu) is a neutral term for any crossbred organism, often used in breeding contexts. 雑種 (zasshu) is more common in everyday speech for mixed-breed dogs or cats, but can imply 'mongrel' if used negatively. In scientific contexts, 雑種 is the standard translation for 'hybrid'.
There is no single Japanese word that perfectly matches the English noun 'crossbreed' in all contexts. Use 交配種 for formal/breeding contexts, 雑種 for pets, or ハイブリッド for plants/technology.
