A breed is a domesticated subspecies or infrasubspecies of an animal. Domesticated animals, plants, and other organisms are those whose collective behavior, life cycle, or physiology has been altered as a result of their breeding and living conditions being under human control for multiple generations. ... In taxonomy, a subspecies is the taxon immediately subordinate to a species. ... An infrasubspecies is a category of organisms of rank lower than subspecies. ... Phyla Porifera (sponges) Ctenophora (comb jellies) Cnidaria Placozoa Bilateria Acoelomorpha Orthonectida Rhombozoa Myxozoa Superphylum Deuterostomia    Chordata (vertebrates, etc. ...

A breed is not completely analogous to the equivalent term for domesticated plants, which is a cultivar. An important difference is that plants are commonly propagated by striking or grafting cuttings. There is no corresponding technique for animals. Cloning may change this if it becomes more available. Divisions Green algae Land plants (embryophytes) Non-vascular embryophytes Hepatophyta - liverworts Anthocerophyta - hornworts Bryophyta - mosses Vascular plants (tracheophytes) Seedless vascular plants Lycopodiophyta - clubmosses Equisetophyta - horsetails Pteridophyta - true ferns Psilotophyta - whisk ferns Ophioglossophyta - adderstongues Seed plants (spermatophytes) †Pteridospermatophyta - seed ferns Pinophyta - conifers Cycadophyta - cycads Ginkgophyta - ginkgo Gnetophyta - gnetae Magnoliophyta - flowering plants... A cultivar is a cultivated variety of a plant species. ... Cloning is the process of creating an identical copy of an original. ...

A breed should also be distinguished from a strain, which is simply the descendants of a single significant individual, and which in domesticated animals is also known as a bloodline. A strain may not remain entirely within a breed, nor is a breed necessarily composed of a single strain.

For a type to be recognised as a breed, there should be a viable true-breeding population. See also selective breeding, genotype, phenotype. Selective breeding in domesticated animals is the process of developing a cultivated breed over time. ... The genotype is the specific genetic makeup (the specific genome) of an individual, usually in the form of DNA. It codes for the phenotype of that individual. ... The phenotype of an individual organism is either its total physical appearance and constitution, or a specific manifestation of a trait, such as size or eye color, that varies between individuals. ...
