Study Guide for Genetics supplements Genetics, third edition, by Daniel Hartl, and follows the chapter organization and general content of the parent book. The material is drawn from the author's teaching of genetics, and it, therefore, includes alternative explanations of the same basic facts and concepts. With its concentration on the most pertinent aspects of the subject, it offers rapid access to, and overviews of, the material. As such, it will be useful both as a guide to the parent book, and a review of fundamental elements of genetics.
