Building on the proven strengths of Russell's step-by-step problem-solving approach, Essential iGenetics blends a classic, Mendel-first approach with modern molecular coverage. This easy to read introduction to genetics presents full coverage of the subject in a brief and manageable format. The text covers basic genetics principles, with balanced coverage of Mendel, historical experiments, and cutting-edge chapters on Genome Analysis and Molecular Evolution. Students develop and apply critical thinking skills as they work step-by-step through a number of solved genetics problems. Students can also apply the principles and techniques learned to a variety of problems at the end of each chapter.


  • Step-by-step problem sets throughout the book represent a wide range of topics and difficulty levels, and give students practice in problem solving.
  • The text includes cutting-edge coverage of Genome Analysis and Molecular Evolution.
  • The Essential iGenetics Web site , free with every new text, includes 50 animations, 24 iActivities, and 600 practice quizzes that help students grasp abstract processes and participate in active problem solving. Building on chapter-opening case studies, the iActivities present real-life genetics problems that help develop students' critical thinking skills and actively engage them in applying their understanding of genetics.
  • Media flags throughout the text direct students to narrated animations on the Essential iGenetics Website . These animations (all scripted and developed by Peter Russell) help students visualize challenging concepts and dynamic processes. For example, animations of meiosis and recombinant DNA bring text images to life by taking students through a process from start to finish, thereby reinforcing the key concept.
  • Experimental data in the text and on the web site emphasizes an inquiry-based approach and engages students in the process of science. For example, one iActivity investigates the part of the gene responsible for cystic fibrosis and tries to identify possible causes of the disease using real data.
  • Pedagogy:
    • Principal Points, appearing at the beginning of each chapter, alert students to key concepts.

    • Keynotes, at the end of each new topic within a chapter, summarize important ideas and allow students to check their progress.

    • Summaries at the end of each chapter tie all the main points together.

    • Analytical Approaches at the end of each chapter guide students step-by-step through genetic problems.

  • Human examples help students comprehend new molecular understandings of various human genetic diseases.
  • The Diagnostic Pre-Test, at, allows instructors to estimate the degree of student knowledge before class begins.

Peter J. Russell received his B.S. in Biology from University of Sussex in 1968 and his Ph.D. in Genetics from Cornell University in 1972. He then joined the Biology faculty of Reed College in 1972 where he is currently Professor of Biology. Russell teaches an upper-division genetics and molecular biology lecture/laboratory course, the genetics section of the introductory biology course, an advanced seminar course in yeast virology, and advises senior thesis research students. He is also the author of a number of successful genetics textbooks.

He is currently studying the molecular genetics of the replication of double-stranded (ds) RNA viruses found in budding yeast, Saccharomyces cerevisiae. The research goals are to define in vivo the cis-acting sequences that are required for viral RNA packaging into capsids and for genome replication, and to identify and characterize any yeast gene products required for virus propagation. His earlier research involved Neurospora RNA synthesis and the organization of and regulation of the number of ribosomal RNA genes, and nitrogen metabolism in the pathogenic dimorphic yeast Candida albicans.
