Introduction to Genetics: A Molecular Approach is a new textbook for first and second year undergraduates. It explains transmission genetics by first presenting molecular structures and mechanisms before introducing the more challenging concepts and terminology associated with transmission genetics. Then the text addresses the role of genetics in the world today, from agriculture and industry to medicine and forensics. Genetics is a practical subject and the experimental basis of genetics is explained throughout the text in discrete "Research Briefings." Extensive end-of-chapter questions include definitions and conceptual problems. Other supplements include the art program in PowerPoint and JPEG formats; animations; and a question bank and lecture slides for instructors.
