Detailed explanation-1: -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.
Detailed explanation-2: -Artificial selection is the identification by humans of desirable traits in plants and animals, and the steps taken to enhance and perpetuate those traits in future generations.
Detailed explanation-3: -Humans have selectively bred plants and animals for thousands of years including: crop plants with better yields. ornamental plants with particular flower shapes and colours. farm animals that produce more, better quality meat or wool.
Detailed explanation-4: -Selective breeding is a form of genetic modification which doesn’t involve the addition of any foreign genetic material (DNA) into the organism. Rather, it is the conscious selection for desirable traits.
Detailed explanation-5: -Artificial selection is an evolutionary process in which humans consciously select for or against particular features in organisms – for example, by choosing which individuals to save seeds from or breed from one generation to the next. People have been artificially selecting plants and animals for thousands of years.
