Explanation:
Purebreds
Purebreds are the result of true breeding where specimens breed true-to type when mated like-to-like. The idea is that the purebred has fundamental characteristics that are consistent, replicable and predictable. Pure breeding is of necessity carried out from a restricted gene pool which has been a cause for concern. As the positive characteristics of any species or type are perpetuated through true breeding so are the undesirable traits which are a result of inbreeding. The limited gene pool leaves purebred products susceptible to a range of congenital health issues particularly where the emphasis is on aesthetics.
Hybrids
A hybrid organism is one with parentage of two different species. In the animal kingdom, mules (horse and donkey), ligers (tiger and lion), yakalos (yak and buffalo) and so on are familiar hybrids. There are various types of hybrids possible. The most obvious kind is offspring resulting from the interbreeding of two species. The second kind is hybrids between different subspecies which include intra-specific (between subspecies), intergeneric (between genera) and interfamilial hybrids. The third sort of hybrid is that caused by selective breeding to enhance and make consistent desirable characteristics such as heat tolerance amongst certain breeds of cattle.
An organelle could be the nucleus of a cell.
The nucleus of a cell would be comparable to the nervous system in the body, which is considered an organ system.
