The book "Modern genetics in 3 tons" by F. Ayala and J. Kayger is a fascinating and deep dive into the world of genetics, which continues to be one of the most relevant and dynamically developing areas of science. This three-volume edition offers readers not only the theoretical underpinnings but also the practical aspects that make it indispensable for students, faculty, and anyone interested in contemporary advances in biology and medicine. The first volume of the book introduces the reader to the basics of genetics, starting with classical concepts such as heredity and variation, and ending with modern methods of molecular genetics. The authors masterfully explain complex scientific ideas, making them available to a wide audience. Each section is filled with real-life examples and relevant research, which allows the reader not only to learn the material, but also to see its practical application. The second volume focuses on more complex topics such as genetic engineering, genomics, and bioinformatics. Here, readers will be able to learn about recent advances in gene editing, such as CRISPR, and their potential impact on medicine and agriculture. The authors raise important ethical issues related to manipulation at the genetic level, which makes the book relevant not only for specialists, but also for the general public interested in the consequences of scientific discoveries. The third volume completes the trilogy, devoting attention to evolutionary genetics and population genetics. Here, readers will be able to learn about how genetics helps to understand the mechanisms of evolution, adaptation, and diversity of living organisms. The authors suggest that readers look at genetics as a tool that helps unlock the mysteries of nature and explain how life on Earth adapts to changing conditions. This book will be interesting not only for undergraduate and graduate students studying biology and medicine, but also for teachers, researchers and anyone who wants to be aware of the latest achievements in the field of genetics. It is suitable for both beginners and those who already have experience in this field, due to its affordable style of presentation and rich content. F. Ayala and J. Kayger authors known for their scientific works and active scientific activity. Their previous works, such as "Genetics for All" and "Basics of Molecular Biology", have also gained recognition in the scientific community and have become major textbooks for students. In Modern Genetics in 3 T, they continue their tradition of accessible and interesting exposition of complex things, which makes their books indispensable for anyone who wants to understand how life works at the molecular level. The book “Modern Genetics in 3 tons” is not just a textbook, it is a real guide to the world of genetics, which inspires study and research. It raises important topics such as ethics in science, the impact of genetics on human health and the future of humanity in the light of scientific discoveries. If you are looking for literature that will help you understand the complex issues of genetics and give you the opportunity to see how science affects our lives, this book will be an excellent choice.
