Instructors will find this Seventh Edition of HUMAN HEREDITY current, clear, and complemented by an amazing array of technology for students and instructors. In addition, the latter chapters (12-19) have been reorganized for greater ease of use. There is also more coverage of hot topics like recombinant DNA technology, genetic engineering, cloning, stem cell research, and HIV. In support of this, "How Would You Vote?" questions appear at the beginning and end of each chapter. Chapters begin with an opening story-focusing on a controversial issue. After the story, the "How Would You Vote?" box directs students to the website to voice their opinion. On the website the issue is summarized, an InfoTrac activity with questions involving the issue is provided, and students cast their vote and see tallied results of the voting. Additional student support includes Human GeneticsNOW, a password-protected website integrated with the Seventh Edition that provides students with access to diagnostic Pre-Tests and Post-Tests for each chapter. It automatically generates customized learning plans for students, directing them to text information and ancillaries that help them master specific concepts. Active Figures in the text, indicated by a media icon, have corresponding narrated animations on the Human GeneticsNOW site that are included in the customized Learning Plan along with additional animations and media assets. For instructors, a Multimedia Manager provides the all of the art and photos from the text in PowerPoint form, and, lectures can be further enhanced by using animations and CNN videos on human heredity topics.
