Throughout the years, many crops and domestic animals have been selectively bred for desirable traits. for example, domestic dogs have been bred for characteristics such as temperament, color, and size. how can selective breeding change the genetic makeup of such species?

The selective breeding helps to maintain pure breed and hence exclude the hybrids.

Selective breeding is a very commonly practiced procedure in plant management and animal husbandry. This selective breeding helps to achieve and maintain the homozygous traits of selective characters. For example, if two dogs with white colour are breed, then their progenies will be white too. Thus the selective character i.e fur color will be maintained.

In crops, if the plants with desired fruit characteristics are bred with each other then superior quality of fruits are achieved and maintained over generations. This is very essential economically too.
