Answer/Example : A farmer crosses two kinds of corn. He produces a new, better tasting type of corn. -Holy122

Artificial selection occurs when a likeable trait is found within a member of a species. Said species is then either outcrossed or inbred with another member of the species to pass on and refine the trait. After a period of time the genes will hopefully be 'fixed' into the population.
An example of artificial selection was in England a few centuries ago when people would breed together pigeons with long tail feathers to create pigeons that had longer and longer tail feathers, which where used in women's hats. Another everyday example of artificial selection is how farmers breed together certain animals to get desirable traits (like breeding together certain cows to get one that will produce the tastiest beef or something.)
a dog breed is a group of genetically and phenotypically similar dogs sharing characteristic traits and bred from a stock of individuals which were selected for these traits.
False, dog breeding would be an example of Artificial Selection.

artificial selection
As an example of the selective mechanism, but artificial selection is directed by men and usually has a definite goal in mind. Natural selection is the selection of favorable variants, something like artificial selection, against the backdrop of the immediate environment. Artificial selection selects traits beneficial to the men doing the selection, while natural selections selects traits beneficial to the organism. Still, genes are changed over time in populations with both methods.
Natural selection is when contemporary species rose from ancestors that survived due to their physical characteristics in their habitats. A well-known example is the Galapagos Islands and how the animals on the islands adapted to their environments. Darwin convinced the biology world that diversity in organisms came from evolution (descent without modification). Artificial selection is when humans intentionally breed animals for certain traits. Unlike natural selection, where only the fittest survive, artificial selection is for human's likings. Many crops that are grown are part of artificial selection.
Some theorems on artificial selection was created in 1934.
Cows that give more milk than other cows are an example of selective breeding for increased milk production. This process involves choosing cows with desirable traits, such as high milk production, and breeding them to pass on these traits to future generations. Over time, this can lead to a population of cows that consistently produce more milk than the original population due to genetic selection.
Nature plays no direct role in artificial selection. That is the difference between artificial selection and natural selection. Nature does play some indirect roles in artificial selection. One indirect role is in providing the organisms with which one beings the artificial selection. Another is in influencing the choices of the organism performing the artificial selection.
Variation in the organisms under selection. In both artificial selection and natural selection there must be heritable variations that have the possibility of being in the case of artificial selection what the selector wants in the organism and in thje case of natural selection survivability and reproductive advantages.
