Advanced undergraduate textbook covering the essential analytical tools needed in genetic analysis. Text boxes highlight key questions and examples.
...succeeds in provoking students to think like geneticists...its emphasis on foundational principles sets it apart from many of its contemporaries. I heartily recommend it. Although the book is intended for advanced undergraduates, its analytical approach, combined with a strong emphasis on principles, could lend itself to reading by first-year students. Paul B. Rainey, Times Higher Education Supplement, March 2004 "Necessarily the text is detailed and highly technical in content, but the literary style is direct, lively and personal...Overall, this book is an accessible and well-presented reference resource." Chris Clegg, Journal of Biological Education, August 2003 "This is a book that you will want to own. It is the only text in which I have found definitive explanations of several key concepts that are presented in the course. The primary author, Scott Hawley, is an accomplished Drosophila geneticist who takes the education of new geneticists very seriously." Steve Mount, University of Maryland "Geneticists are certain to go on devising further ingenious screens and methods for analysis, exploiting advances in technology and novel ideas, but always building on the same basic strategies. This book should help to inspire new and deeper experimentation; I recommend it strongly to any serious practitioner of genetics, and particularly to any graduate student embarking on research in genetics." Jonathan Hodgkin, University of Oxford, BioEssays, June 2004
