An invaluable student-tested study aid, this primer provides guided instruction in the analysis and interpretation of genetic principles and problem solving. Each section is introduced with a summary of key concepts and an overview of the topic with key terms. A series of problems, graded from simple to more complex, then allows students to test their understanding of the material. Each question and answer is provided with a detailed explanation. A glossary of genetic terminology also provides quick access to basic information for the geneticist and non-geneticist alike. This new edition includes additional problems, extensively expanded coverage of molecular biology, new ‘overview’ chapters to give additional study hints and perspectives, crossword puzzles to test knowledge of terms, historical landmarks, and new reference tables. Students at all levels will find this book to be a valuable aid. It will complement any genetics textbook, or can stand alone as a review manual.
