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.
Well, a purebred is made by one kind of something, let's use birds as an example. If two Red-lored Amazons had baby birds together, that would be a pure bred. However, if a Yellow-naped Amazon and a Red-lored Amazon had babies together, it would be a hybrid, which are not as much money as purebreds. It means 100% of its breed. For example, a purebred golden retriever would be 100% golden retriever. What purebred means is that it's all the same....if you were doing a punnett square you would do SS or TT or ss or tt. Purebred means that cultivation of a species of animal through selective breeding. Based on my research as to what the differences are, purebreds are pure, from the word itself. For example, white combined with white or purple with purple. Hybrids, on the other hand, are produced through cross breeding; i.e. they're a composite of mixed origin.
