Not all purebred animals have their lineage in written form. For example, until the 20th century, the Bedouin people of the Arabian Peninsula only recorded the ancestry of their Arabian horses via an oral tradition, supported by the swearing of religiously based oaths as to the asil or "pure" breeding of the animal. Conversely, some animals may ...
A mule is a sterile hybrid of a male donkey and a female horse.Mules are smaller than horses but stronger than donkeys, making them useful as pack animals.. In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction.
Selective breeding can be unintentional, for example, resulting from the process of human cultivation; and it may also produce unintended – desirable or undesirable – results. For example, in some grains, an increase in seed size may have resulted from certain ploughing practices rather than from the intentional selection of larger seeds.
Breeding stock is a group of animals used for the purpose of planned breeding. When individuals are looking to breed animals, they look for certain valuable traits in purebred animals, or may intend to use some type of crossbreeding to produce a new type of stock with different, and presumably superior abilities in a given area of endeavor. For ...
The Old Irish landrace goat is present in the Burren mountains, although fewer than 10% of the remaining feral herd (an estimated 250) is believed to be purebred, due to crossbreeding with Anglo-Nubian and Swiss imports. [12] [13] [14] Recent DNA profiling has verified that this population is genetically distinct from other strains of goat.
A dog is said to be purebred if their parents were purebred and if the dog meets the standards of the breed. The American Kennel Club allows mixed-breed dogs to be shown but under the condition the animals have been spayed or neutered, are not a wolf hybrid, and not eligible for the AKC Foundation Stock Service Program or an AKC Purebred ...
Mother Nature took no prisoners when she unleashed her wrath on Los Angeles at the beginning of 2025. Wildfires continue to rage in the area, and the death toll now stands at at least 27.
In such cases, selection criteria in nature differ from those found in domesticated conditions. Because of this, domesticated animals often differ significantly in phenotype, behaviour and genetics from their wild forerunners. It is the hope of breeding-back programs to re-express, within a new breeding lineage, the wild, ancient traits that ...
