From Wikipedia, the free encyclopedia. A true breeding organism, sometimes also called a purebred, is an organism that always passes down certain phenotypic traits (i.e. physically expressed traits) to its offspring.n organism is referred to as true breeding for each trait to which this applies, and the term true breeding is also used to describe individual genetic traits.
Crossbreeding, sometimes called designer crossbreeding , refers to the process of breeding such an organism, often with the intention to create offspring that share the traits of both parent lineages, or producing an organism with hybrid vigor.hile crossbreeding is used to maintain health and viability of organisms, irresponsible crossbreeding can also produce organisms of inferior quality or dilute a purebred gene pool to the point of extinction of a given breed of organism.
