Principles of Genetics, 6e balances key content and problem solving so that students can apply what they are reading to help solve related problems. Instructors and students can feel confident that they have the following in–text tools and supplements they need to succeed in the genetics course:
- Test Your Problem–Solving Skills feature shows students how to approach and solve a key problem. In addition, a Solve It icon prompts students to go online to work with animated tutorials. Practice problems for all question types are found at the end of each chapter.
- The Focus On boxes (one per chapter) have been revised to include the most current developments in genetics as well as the most relevant topics to students.
- A streamlined topical coverage, vetted by a panel of genetics instructors, makes for a text that is manageable in size. This textbook will provide instructors and students with in–depth explanations of key topics frequently covered in a one–semester course.
- Animated solutions to the Solve It prompts in the text utilize Camastia Studio software, a registered trademark of TechSmith Corporation. There tutorials provide step–by–step solutions that appear as if they are written out by hand as an instructor voice–over explains each step.
- GO Problem tutorials help students build confidence as they observe a problem being worked out and then attempt to solve a similar problem on their own.

D. Peter Snustad is a Professor Emeritus at the University of Minnesota, Twin Cities. He received his B.S. degree from the University of Minnesota and his M.S. and Ph.D. degrees from the University of California, Davis. He began his faculty career in the Department of Agronomy and Plant Genetics at Minnesota in 1965, became a charter member of the new Department of Genetics in 1966, and moved to the Department of Plant Biology in 2000. During his 43 years at Minnesota, he taught courses ranging from general biology to biochemical genetics. His initial research focused on the interactions between bacteriophage T4 and its host,
E. coli. In the 1980s, his research switched to the cytoskeleton of
Arabidopsis and the glutamine synthetase genes of corn. His honors include the Morse–Amoco and Dagley Memorial teaching awards and election to Fellow of the American Association for the Advancement of Science. A lifelong love of the Canadian wilderness has kept him in nearby Minnesota.
Michael J. Simmons is a Professor in the Department of Genetics, Cell Biology and Development at the University of Minnesota, Twin Cities. He received his B.A. degree in biology from St. Vincent College in Latrobe, Pennsylvania, and his M.S. and Ph.D. degrees in genetics from the University of Wisconsin, Madison. Dr. Simmons has taught a variety of courses, including genetics and population genetics. He has also mentored many students on research projects in his laboratory. Early in his career he received the Morse–Amoco teaching award from the University of Minnesota in recognition of his contributions to undergraduate education. Dr. Simmons s research focuses on the genetic significance of transposable elements in the genome of Drosophila melanogaster. He has served on advisory committees at the National Institutes of Health and was a member of the Editorial Board of the journal Genetics for 21 years. One of his favorite activities, figure skating, is especially compatible with the Minnesota climate.
