NEET BIOLOGY

Detailed explanation-1: -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-2: -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-3: -Selective breeding makes use of existing, naturally present gene variants in a species? and the natural process of breeding. Genetic engineering involves a direct change to an organism’s genome in the laboratory. Gene variants made through genetic engineering can be passed from one generation to the next.

Detailed explanation-4: -Artificial selection is the process by which humans choose individual organisms with certain phenotypic trait values for breeding. If there is additive genetic variance for the selected trait, it will respond to the selection, that is, the trait will evolve.

Detailed explanation-5: -Eugenics is essentially selective breeding applied to humans.
