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.
Artificial reproduction is the re-creation of life brought about by means other than natural ones. It is new life built by human plans and projects. Examples include artificial selection, artificial insemination, in vitro fertilization, artificial womb, artificial cloning, and kinematic replication.
Artificial selection involves the deliberate exploitation of knowledge about genetics and reproductive biology in the hope of producing desirable characteristics in descendant organisms. It is widely practiced in agriculture , but it may also be unintentional and may produce unintended results.
Sexual selection creates colourful differences between sexes in Goldie's bird-of-paradise.Male above; female below. Painting by John Gerrard Keulemans.. Sexual selection is a mechanism of evolution in which members of one sex choose mates of the other sex to mate with (intersexual selection), and compete with members of the same sex for access to members of the opposite sex (intrasexual ...
Artificial Selection and Selective Breeding are distinguished both by process and outcome. Artificial Selection is a process by which humans or other organisms, through a process of elimination or reproductive restriction, select which members of a population of organisms will reproduce. This process differs from Natural Selection in that the individuals selected to survive and reproduce do ...
A selectable marker is a gene introduced into cells, especially bacteria or cells in culture, which confers one or more traits suitable for artificial selection.They are a type of reporter gene used in laboratory microbiology, molecular biology, and genetic engineering to indicate the success of a transfection or transformation or other procedure meant to introduce foreign DNA into a cell.

The term "apostatic selection" was introduced in 1962 by Bryan Clarke in reference to predation on polymorphic grove snails and since then it has been used as a synonym for negative frequency-dependent selection. [2] The behavioural basis of apostatic selection was initially neglected, but was eventually established by A.B Bond. [3]
