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: -The domestic horse is known to have been strongly impacted by artificial selection, and was often selected for functional traits.

Detailed explanation-3: -Dog breeding is another prime example of artificial selection. Although all dogs are descendants of the wolf, the use of artificial selection has allowed humans to drastically alter the appearance of dogs.

Detailed explanation-4: -A common example of artificial selection in animals is dog breeding. As with racehorses, particular traits are desirable in different breeds of dogs that compete in dog shows. The judges look at coat coloring and patterns, behavior, and even teeth.

Detailed explanation-5: -Due to artificial selection for better racing ability, this breed also shows superior performance characteristics such as large lung volume, high maximum haemoglobin concentration and cardiac output, large muscle mass to body weight ratio, high skeletal muscle mitochondrial density, and oxidative enzyme activity [3–6].
