Tony Griffiths would like to acknowledge the pedagogical insights of David Suzuki, who was a co-author of the early editions of this book, and whose teaching in the media is now an inspiration to the general public around the world. Great credit is also due to Jolie Mayer-Smith and Barbara Moon, who introduced Tony to the power of the constructivist approach applied to teaching genetics. Sean Carroll would like to thank Leanne Olds for help with the artwork for Chapters 11, 12, 13, 14, and 20. John Doebley would like to thank his University of Wisconsin colleagues Bill Engels, Carter Denniston, and Jim Crow, who shaped his approach to teaching genetics.

The authors also thank the team at W. H. Freeman for their hard work and patience. In particular we thank our developmental and supplements editor, Erica Champion; senior acquisitions editor Lauren Schultz; senior project editor Jane O’Neill; and copy editor Teresa Wilson. We also thank Susan Wein, production supervisor; Diana Blume, art director; Vicki Tomaselli, cover and text designer; Sheridan Sellers, page layout; Janice Donnola, illustration coordinator; Jennifer MacMillan, permissions manager; Amanda Dunning, executive media editor; and Alexandra Garrett, editorial assistant. Finally, we especially appreciate the marketing and sales efforts of John Britch, executive marketing manager, and the entire sales force.
