Explanation:
Artificial selection, also called "selective breeding”, is where humans select for desirable traits in agricultural products or animals, rather than leaving the species to evolve and change gradually without human interference, like in natural selection. Traits that help an organism to survive will allow it to survive long enough to reproduce and will be passed on the most to the next generation. If a trait does not help or hurts the organism, it will be less likely to survive and as a result will be less likely to be passed on.
