That genetics is not a static body of knowledge is one of the fundamentals behind this text. Historical and contemporary experimental examples are therefore used throughout. The authors believe that genetics makes sense of evolution. Therefore, this volume presents concepts in an evolutionary context whenever possible. In addition, the text uses human examples to illustrate genetic concepts so that the student will see practical applications of genetic analysis. A study guide to accompany this text will be available (ISBN 0-471-15284-6).
