Crossbreeding refers to the practice of breeding purebred animals of two different varieties (e.g. a poodle and a Labrador.) The concept of crossbreeding is useful to breeders in several ways. It can be used, for example, to create new hybrid varieties that combine favorable characteristics from different purebred strains into new strain. It also allows breeders to strengthen purebred strains and avoid excessive inbreeding by introducing genetic diversity from other populations. In this case, crossbreeding is followed by selective breeding with the purebred population in order to maintain the positive impact of increased diversity while reducing noticeable divergences from breed characteristics that may occur in the initial crossbreed.
