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.
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 ...
Zebras of the project in the animal camp on the slopes of Devil’s Peak, above Groote Schuur Hospital, Cape Town, South Africa. The Quagga Project is an attempt by a group in South Africa to use selective breeding to achieve a breeding lineage of Burchell's zebra (Equus quagga burchellii) which visually resemble the extinct quagga (Equus quagga quagga).
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 ...
The breeding of farm animals seldom occurs spontaneously but is managed by farmers with a view to encouraging traits seen as desirable. These include hardiness, fertility, docility, mothering abilities, fast growth rates, low feed consumption per unit of growth, better body proportions, higher yields, and better fibre qualities.

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 ...
