This title is a Pearson Global Edition. The Editorial team at Pearson has worked closely with educators around the world to include content which is especially relevant to students outside the United States.

Keep Your Course Current and Relevant

• Two new Special Topics in Modern Genetics mini-chapters explore cutting-edge topics, including CRISPR-Cas and Genomic Editing and Advances in Neurogenetics: The Study of Huntington Disease.
• • All Special Topics chapters include a series of questions that help students review key ideas or facilitate personal contemplations and group discussions.
  • Assessment questions for Special Topics in Modern Genetics Chapters are assignable in Mastering Genetics.
• Reorganized and expanded coverage of gene regulation in eukaryotes reflects recent discoveries that reveal how RNA in many forms plays critical roles in the regulation of eukaryotic gene activity. A single chapter on this topic in previous editions has been expanded to three: Transcriptional Regulation in Eukaryotes (Chapter 17), Posttranscriptional Regulation in Eukaryotes (Chapter 18), and Epigenetics (Chapter 19).
• An increased emphasis on ethical considerations helps students think through ethical aspects of genetics-related issues. Essays that used to be known as Genetics, Technology, and Society have been replaced or revised as Genetics, Ethics, and Society. In addition, each chapter ends with a Case Study, each of which raises ethical questions.
• Modern Approaches to Understanding Gene Function feature challenges students to understand how modern gene targeting approaches (such as the use of transgenic animals, knockout animals, and RNA interference) have dramatically advanced our understanding of gene function. Each entry highlights representative experimental approaches, analyzes experimental data, and relates to a concept discussed in the chapter. Each feature includes questions for further analysis or discussion.

Motivate Students to Develop and Practice Problem-solving Skills

• Updated! Mastering Genetics is an online homework and assessment program that guides students through complex topics in genetics, using in-depth tutorials that coach students to correct answers with hints and feedback specific to their misconceptions and errors. See “Personalize Learning with Mastering Genetics.”
• Now Solve This Problems are integrated throughout each chapter to test student knowledge while learning chapter content. Exercises include a hint to guide students and a brief answer is provided in the appendix. One Now Solve This problem per chapter is linked to related end of chapter problems to make it easier for professors to assign similar problems for homework.
• Insights and Solutions sections strengthen students’ problem solving skills by showing step-by-step solutions and rationales for select problems.
• Problems and Discussion Questions are found at the end of every chapter and most are assignable in Mastering Genetics.
• Extra Spicy Problems challenge students to solve complex problems, many based on data derived from primary genetics literature.
• How Do We Know? questions appear as the first entry in the Problems and Discussion Questions and ask students to identify the experimental basis underlying important concepts and conclusions—that is, how we know what we know. Students are asked to review numerous findings discussed in the chapter and to summarize the process of discovery that was involved.

Emphasize the Fundamental Ideas of Genetics

• A Concept Question, found as the second question in the Problems and Discussion Questions,

Engage Students in Active and Cooperative Learning

• Genetics, Ethics, and Society essays provide a synopsis of an ethical issue related to a current finding in genetics that impacts directly on society today. It includes a section called Your Turn, which directs students to related resources of short readings and websites to support deeper investigation and discussion of the main topic of each essay.
• Case studies at the end of each chapter have been updated with new topics. Students can read and answer questions about a short scenario related to one of the chapter topics. The Case Studies link the coverage of formal genetic knowledge to everyday societal issues, and they include ethical considerations.
