Many investigators seem to be fascinated by the coat colors of the mam mals with which they work. This seems to be the case particularly for those utilizing isogenic strains of mice, not only because such strains display wide ly different phenotypes, but because scientists, by definition, are an inquisi tive lot and it is sometimes difficult for the uninitiated to comprehend how such phenotypes are produced. This bewilderment becomes even more ap parent if the investigator happens to be involved in breeding studies and a number of attractively colored animals, quite different from the original stocks, appear. Thus I can recall numerous occasions when my colleagues, frequently working in areas completely unrelated to any aspect of genetics, have come to me with an attractively pigmented animal or, more likely, with a popUlation of segregating coat color types (usually because they have not tended their animals properly and have ended up with a cage full of F 2S displaying a number of different colors). How, they ask, do such colors come about? While in some cases it is easy to take chalk in hand and explain what has been going on (segregating) and why, in other cases it is virtually impossible. It is extremely difficult because while the interactions of many coat-color factors obey the simple laws of heredity and of predictable gene interactions, others do not.
Serving the needs of pigment cell biologists, cellular physiologists, developmental geneticists, researchers interested in melanoma and more, this new book showcases a blend of new technologies and new insights in the field of pigmantary genetics of mice, with comparative information on other animals. Graduate students can learn here the terminology and scope of the field, and animal fanciers can discover the genetics behind common color variants of mammals. The book is hailed for being written by four of the premier scientists in the field. These authors aim to present the molecular /cellular work in the context of phenotype and the interacting functions of genes that direct the development and function of one biological system. For other researchers, the depth of genetic knowledge on the pigmantary system makes it a valuable model for the study of other systems.
A study showing the importance of domestic animals to the development of human civilisation.
US-Japan meetings on laboratory animal science have been held virtually every year since 1980 under the US-Japan Cooperative Program on Science and Technology. Over the years these meetings have resulted in a number of important documents including the Manual of Microbiologic of Monitoring of Laboratory Animals published in 1994 and the article Establishment and Preservation of Reference Inbred Strains of Rats for General Purposes published in 1991. In addition to these publications, these meetings have been instrumental in increasing awareness of the need for microbiologic monitoring of laboratory rodents and the need for genetic definition and monitoring of mice and rats.
A geneticist discusses the role of DNA in the evolution of life on Earth, explaining how an analysis of DNA reveals a complete record of the events that have shaped each species and how it provides evidence of the validity of the theory of evolution.
Making Mice blends scientific biography, institutional history, and cultural history to show how genetically standardized mice came to play a central role in contemporary American biomedical research. Karen Rader introduces us to mouse "fanciers" who bred mice for different characteristics, to scientific entrepreneurs like geneticist C. C. Little, and to the emerging structures of modern biomedical research centered around the National Institutes of Health. Throughout Making Mice, Rader explains how the story of mouse research illuminates our understanding of key issues in the history of science such as the role of model organisms in furthering scientific thought. Ultimately, genetically standardized mice became icons of standardization in biomedicine by successfully negotiating the tension between the natural and the man-made in experimental practice. This book will become a landmark work for its understanding of the cultural and institutional origins of modern biomedical research. It will appeal not only to historians of science but also to biologists and medical researchers.
Explores the Newly Discovered Link Between Nutrition and EpigeneticsCurrent research suggests that nutrients are more than just food components and that certain nutrients can impact the expression of genes that lead to the development of chronic diseases. With contributions from experts in both fields, Nutrients and Epigenetics examines the epigene
