This best-selling textbook, known for its prominent authorship, exposes students to the landmark experiments in genetics, teaching them how to analyze experimental data and draw their own conclusions based on scientific thinking. The 10th edition has been updated with key advances in genetics and cutting-edge experiments and techniques. New co-author John Doebley, a highly respected population geneticist, brings a fresh, student-driven perspective to completely new chapters on Population and Quantitative Genetics. The key chapters on Evolutionary Genetics and The Evolution of Genes and Traits have been heavily revised to reflect recent discoveries in these areas. The end-of-chapter problems have also been revised and updated, giving students great new exercises to test their understanding. The book is supported by a companion website (www.whfreeman.com/iga10e), which provides online quizzing with feedback and 45 FLASH Animations on core concepts or processes in Genetics.
