An Introduction to Genetic Analysis Preface Genetics and Education Genetics has become an indispensable component of almost all research in modern biology and medicine. Research publications investigating any biological process, from the molecular level all the way to the population level, use the “genetic approach" to gain understanding of that process. Thus, no student of the life sciences can afford to be ignorant of the science of genetics. Genetics has also risen to a position of prominence in human affairs. Special types of plants, animals, and microbes have been developed for human foods, drugs, and myriad other uses. Molecular genetics is the central foundation of the burgeoning biotechnology industry. At the philosophical level, genetics has presented humans with a large number of ethical dilemmas, which regularly surface in the media. Some examples are genetically modified foods, eugenics, privacy of genetic information about individuals, and loss of genetic diversity in nature. Students must be knowledgeable about genetics in order to understand these issues and make informed decisions about them. Lastly, genetic insight has radically affected the human worldview the way we see ourselves in relation to other organisms.

The Balanced Approach to Teaching Genetics Genetics has risen to such prominence through the powerful merger of classical and molecular approaches. Each analytical approach has its unique strengths: classical (organismal) genetics is un-paralleled in its ability to explore uncharted biological terrain; molecular genetics is equally unparalleled in its ability to unravel cellular mechanisms. It would be unthinkable to teach one without the other, and each is given due prominence in this book. Armed with both approaches, students are able to form an integrated view of genetic principles. The partnership of classical and molecular genetics has always presented a teaching dilemma: which of the two partners should the student be introduced to first, the classical or the molecular? We believe that students begin much as biologists did at the turn of the century, asking general questions about the laws governing heredity. Therefore, the first half of the book introduces the intellectual framework of classical eukaryotic genetics in more or less historical sequence. However, molecular information is provided where appropriate. Our students' knowledge base and our years of teaching have together caused us to rethink the traditional organization. In this new edition we have integrated a good deal of molecular genetics into the early chapters. Thus, we reinforce the students' knowledge of DNA structure and function and
