Detailed explanation-1: -The meats sold today are the result of the selective breeding of chickens, cattle, sheep, and pigs. Many fruits and vegetables have been improved or even created through artificial selection. For example, broccoli, cauliflower, and cabbage were all derived from the wild mustard plant through selective breeding.

Detailed explanation-2: -Selective breeding of the disproportionately short legs of breeds such as the Basset Hound and the Dachshund has led to bowed legs and chronic problems with elbow dislocation; the short legs and long back of Dachshunds causes them to suffer more often from ruptured vertebral disks.

Detailed explanation-3: -Selective breeding is a process in which humans breed specific parents to create offspring with desirable characteristics. Examples include dogs bred for specific work tasks or fruit bred to be sweeter.
