The book is a discussion of the science of genetics and how it comes into play in many different jobs. Animal breeders use genetics to create hunting, herding, and guarding animals. Endangered animals have been sustained through captive breeding in zoos. Farmers breed plants for taste, durability, and resistance to disease. Medical researchers use genetics to help diagnose and treat diseases and develop medicines. Criminologists use genetics (in the form of DNA evidence) to help them solve crimes.
