Why is genetics useful to animal breeders?

The field of animal breeding and genetics research is very exciting. Scientists and animal breeders use genetics to produce healthier animals, and better breeds.

Actually, people have been practicing selective breeding of animal for hundreds of years.

A breed is a group of animals that have been bred over a long period of time to look similar in color, size, conformation, and function, and can pass these traits to their off spring. Animal breeders strive to reinforce some genes, and eliminate others. Farmers especially, use selective breeding to improve certain qualities in the next generation of animals. They are interested in using genetic engineering to increase animal productivity, improve resistance to disease, and make the meat that is produce more nutritious.
