A crossbreed, or a crossbred, animal is one with purebred parents of two different breeds, varieties, or populations. The process of breeding a crossbreed animal is known as crossbreeding, which often intends to create offspring that share the desirable characteristics and traits of both parent lineages. Another common intention when it comes to crossbreeding is producing an animal with hybrid vigor (also known as heterosis or outbreeding enhancement), which is the improved or increased function of any biological quality in a hybrid offspring. Heterosis is known as the occurrence of a superior offspring through mixing the desirable genetic contributions of both its parents, which can stem from Mendelian and non-Mendelian inheritance. Crossbreeding is often used to maintain both the health and viability of animals, but irresponsible crossbreeding can also result to offspring of inferior quality or even the dilution of a purebred gene pool to the point of extinction of a specific animal breed.
A domestic animal of unknown ancestry can also be referred to as a crossbreed. In this context, only one parent or grandparent of the animal is known, but the term “mixed breeding” is technically more appropriate and accurate. On the other hand, the term outcross refers to the type of crossbreeding is used within a specific purebred breed in order to increase the genetic diversity within that specific breed, especially in cases when it is essential to avoid inbreeding.
There are systems of crossbreeding for cattle animals. An example is with purebred females that have adapted to a specific environment that are crossed with purebred bulls from another type of environment in order to produce a generation with the traits of both parents. Dogs are also commonly used for crossbreeding, with crossbred animals being popular because of their high hybrid vigor combined with relative attractiveness in the animal.
