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 ...
Charles Roy Henderson (() April 1, 1911 – () March 14, 1989) was an American statistician and a pioneer in animal breeding — the application of quantitative methods for the genetic evaluation of domestic livestock. This is critically important because it allows farmers and geneticists to predict whether a crop or animal will have a desired ...

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.
F1 crosses in animals can be between two inbred lines or between two closely related species or subspecies. In fish such as cichlids , the term F1 cross is used for crosses between two different wild-caught individuals that are assumed to be from different genetic lines.
This "essay" would become two books: The Descent of Man, and Selection in Relation to Sex (1871) and The Expression of Emotions in Man and Animals (1872). The book had been advertised as early as 1865 with the unwieldy title Domesticated Animals and Cultivated Plants, or the Principles of Variation, Inheritance, Reversion, Crossing ...
If the breeding is for a purebred animal that will be used for exhibition or future breeding (pets or livestock), the animal must be registered and conform to the criteria laid out for that breed in a breed standard kept by a central authority, such as a kennel club for dogs. In addition, the breed club, kennel club, or other governing ...
In animal and plant breeding, the use of markers in selection aiming for breeding, mainly the molecular ones, collaborated to the development of marker-assisted selection. While QTL mapping is limited due resolution, GWAS does not have enough power when rare variants of small effect that are also influenced by environment.
