Purebreds are like cultivars of an animal species achieved through the process of selective breeding. When the lineage of a purebred animal is recorded, that animal is said to be pedigreed. Purebreds breed true-to-type which means the progeny of like-to-like purebred parents will carry the same phenotype, or observable characteristics of the ...
Some plants (such as many crops) are primarily self pollenizing and also breed true, so that even under open pollination conditions the next generation will be (almost) the same. Even among true breeding organisms, some variation due to genetic recombination or to mutation can produce a few "off types".
The only true wild (never domesticated) horse in the world today is the Przewalski's horse. Gaited horse , includes a number of breeds with a hereditary intermediate speed four-beat ambling gait, including the Tennessee Walker , Paso Fino , and many others.
A hybrid between two inbred strains can be used to cancel out deleterious recessive genes resulting in an increase in the mentioned areas. This is known as heterosis. [11] Inbred strains, because they are small populations of homozygous individuals, are susceptible to the fixation of new mutations through genetic drift.
Creating true autoflowering seed from two quality, true breeding autoflowering parent plants is easy for most. [20] Breeding new autoflowering strains becomes more difficult when attempting to make a hybrid with a non-autoflowering strain.
The rice plants in the strain can be bred to other rice strains or cultivars, and if desirable plants are produced, these are further bred to stabilize the desirable traits; the stabilized plants that can be propagated and "come true" (remain identical to the parent plant) are given a cultivar name and released into production to be used by ...

The term refers to both breeds and strains that are naturally polled through selective breeding and also to naturally horned animals that have been disbudded. [1] Natural polling occurs in cattle , yaks , water buffalo , and goats , and in these animals it affects both sexes equally; in sheep , by contrast, both sexes may be horned, both polled ...
