Detailed explanation-2: -Selective breeding is also known as artificial selection. Artificial selection is driven by human intervention.
Detailed explanation-3: -For e.g. Early farmers cultivated wild cabbage or Brassica oleracea . This wild cabbage was developed into many varieties such as cabbage, broccoli, kohlrabi, cauliflower, kale, and Brussels by artificial selection and breeding.
Detailed explanation-4: -Chickens, cattle, lambs, and pigs have been selectively bred to produce the available meats we eat today. Artificial selection has enhanced or even developed several fruits and vegetables. Broccoli, cauliflower, and cabbage, for example, were all developed through selective breeding from the wild mustard species.
Detailed explanation-5: -Selective breeding and genetic disorders This process involves the selection and breeding of animals with desirable characteristics, leading to offspring that inherit the same traits.
