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.
Breeding in domestic animals is primarily assortative breeding (see selective breeding). Without the sorting of individuals by trait, a breed could not be established, nor could poor genetic material be removed. Homozygosity is the case where similar or identical alleles combine to express a trait that is not otherwise expressed (recessiveness ...

The first group proposed that animal domestication proceeded along a continuum of stages from anthropophily, commensalism, control in the wild, control of captive animals, extensive breeding, intensive breeding, and finally to pets in a slow, gradually intensifying relationship between humans and animals.

Slave breeding was the practice in slave states of the United States of slave owners systematically forcing slaves to have children to increase their wealth. [1] It included coerced sexual relations between enslaved men and women or girls, forced pregnancies of enslaved women and girls due to forced inter inbreeding with fellow slaves in hopes ...
After initiating his selective breeding program for tameness, Belyayev also began breeding a line of fearful, aggressive foxes. [6] In addition, he started domesticating other animals. He and his team started working with rats in 1972, and later with minks and, briefly, with river otters, although this last experiment was abandoned because the ...
Animal-rearing originated during the cultural transition to settled farming communities from hunter-gatherer lifestyles. Animals are domesticated when their breeding and living conditions are controlled by humans. Over time, the collective behaviour, lifecycle and physiology of livestock have changed radically. Many modern farmed animals are ...
Culling is: ... the rejection or removal of inferior individuals from breeding. The act of selective breeding. As used in the practice of breeding pedigree cats, this refers to the practice of spaying or neutering a kitten or cat that does not measure up to the show standard (or other standard being applied) for that breed.
