Written and oral histories of various animals or pedigrees of certain types of horse have been kept throughout history, though breed registry stud books trace back to about the 13th century, at least in Europe, when pedigrees were tracked in writing, and the practice of declaring a type of horse to be a breed or a purebred became more widespread.
Most mating done by purebred breeders is linebreeding which is the mating of animals of different families within the same breed to bring in desirable traits that are not present in the original animals. [11] Unlike commercial producers, purebred breeders cannot use crossbreeding as it would dilute the breed's purity, resulting in a mixed breed ...
Animal breeding is a branch of animal science that addresses the evaluation (using best linear unbiased prediction and other methods) of the genetic value (estimated breeding value, EBV) of livestock. Selecting for breeding animals with superior EBV in growth rate, egg, meat, milk, or wool production, or with other desirable traits has ...
Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.
Line breeding is differentiated from inbreeding by excluding pairings between parents and offspring, and between full siblings. Outcrossing is the planned breeding between two unrelated dogs, used to increase genetic diversity in a breed and decrease genetic issues or abnormalities inherited from line breeding or inbreeding.
Another point of view is that a breed is consistent enough in type to be logically grouped together and when mated within the group produce the same type. [5] When bred together, individuals of the same breed pass on these predictable traits to their offspring, and this ability – known as "breeding true" – is a requirement for a breed.
The breed is defined by The American Beefalo Association as being genetically at least five-eighths Bos taurus and at most three-eighths Bison bison. [ 4 ] In 2024, a genetic study, including historical samples from Basolo's foundational herd, found that the majority of "Beefalo" cattle who were genomically sequenced (39 out of 47 sampled ...
The ratio of pedigree/purebred cats to random-bred cats varies from country to country. However, generally speaking, purebreds are less than 10% of the total population. [11] As of 2021 in the United States, human owners of cats typically keep cats indoors at all times. [12]
