A crossbreed is an animal or plant that’s a mixture of two different breeds or types. To crossbreed is to produce a creature of this type. If you crossbreed a lion and a tiger, you make a liger.
Geneticists, who study DNA, make crossbreeds when they mix parents with different genes to create a new type of offspring. Often such crossbreeds are new kinds of plants. Different animals can be mixed to create crossbreeds, too. A common example of a crossbreed is with dog breeds, like when a poodle and a schnauzer are bred to create a schnoodle.
