Detailed explanation-1: -Crossbreeding. Crossbreeding involves breeding two unrelated individuals. This is often used to produce offspring with desirable characteristics from two different individuals.
Detailed explanation-2: -Hybridization is one of the two methods of selective breeding. More specifically, in hybridization, breeding occurs between two parents that are genetically dissimilar. Moreover, the parents may belong to different species, different breeds, or cultivars within the same species.
Detailed explanation-3: -Crossbreeding is sometimes used synonymously with hybridization. In particular though, hybridization is a process to produce offspring (referred to as hybrid) by crossing two parents of different species.
Detailed explanation-4: -In animal breeding, techniques such as inbreeding, linebreeding, and outcrossing are utilized. In plant breeding, similar methods are used. Charles Darwin discussed how selective breeding had been successful in producing change over time in his 1859 book, On the Origin of Species.
Detailed explanation-5: -Crossbreeding: Crossbreeding is the mating of two animals of different breeds.
