The book “Principles of Genetics” is widely considered to be one of the best resources for students taking their first genetics class. It reveals the process of exactly how genetics is carried out, which sheds light on the fast developing field of genetic science. In each and every section, the writers place an emphasis on humans and bring attention to the function that geneticists play in order to keep students interested and motivated. Because many diseases and disorders have a component that is inherited, the area of genetics is extremely important to the science of medicine. Newborn babies are now able to be tested for the diagnosis of a number of genetic abnormalities, some of which may only manifest themselves in later stages of development. Some examples of this include inherited diseases like sickle cell anaemia and Huntington’s disease as well as more prevalent conditions like asthma, diabetes, and hypertension. This book offers a comprehensive discussion of a wide variety of genetics-related subjects. In spite of the fact that genetics as a science is still in its infancy, people have known for millennia about the hereditary nature of characteristics and have a general understanding of genetic principles. The application of genetic principles to the process of domesticating plants and animals was the initial step in the development of agriculture. Now, the majority of the crops and animals that are used in agriculture have been subjected to intensive genetic engineering in order to achieve higher yields and other desirable characteristics, such as resistance to disease and pests (for example, Bt cotton), enhanced nutritional qualities (for example, Golden rice), and a number of other characteristics.
