Comparative Mammalian Cytogenetics


Book Description

Ten years ago a symposium on Cytotaxonomy 'was held in London (Proc. Linn. Soc. Lond. 169:110, 1958) in which a first attempt was made to bring together various disciplines to discuss advances of mammalian cytogenetics and to put them into proper context with the sciences of evolution and taxonomy. The introductory remarks by \V. B. Turrill to that symposium, essentially an admonishment to be tolerant of the short comings of our respective disciplines, would be a most appropriate begin ning to this conference as ,,'ell. However, the meeting held at Hanover was conceived more along the lines of remarks made by R. B. Seymour Se,,'ell in his presidential address to the same society: "It has been said that scientists in this search for truth are nowadays too much concerned with the accumulation of facts, and make too little use of their imagina tion in their attempts to explain such facts as they have accumulated. " (In "The continental drift theory and the distribution of the Copepoda," ibid. 166:149, 1956. ) \\Tith this as a background, two years ago we held the first of a series of loosely-structured conferences on reproductive failure in the relaxing atmosphere of this small New England college community. The manu scripts of that meeting have been published (Comparative Aspects of Re productive Failure, Springer-Verlag New York Inc. , 1967).




Coloured Sheep


Book Description

Some skill, some luck and lots of fun: sheep colour genetics is like a game of cards! This book explains the rules of the game. A game of cards helps to visualise the rules that govern colour genetics, introducing terminology on the way and providing practical tips for the reader's own flock.




Handbook of Genetics


Book Description

The purpose of the first four volumes of the Handbook of Genetics is to bring together collections of relatively short, authoritative essays or an notated compilations of data on topics of significance to geneticists. Many of the essays will deal with various aspects of the biology of certain species or species groups selected because they are favorite subjects for genetic investigation in nature or the laboratory. Often there will be an encyclo pedic amount of information available on such species, with new papers appearing daily. Most of these will be written for specialists in a jargon that is bewildering to a novice, and sometimes even to a veteran geneticist working with evolutionarily distant organisms. For such readers what is needed is a written introduction to the morphology, life cycle, reproductive behavior, and culture methods for the species in question. What are its particular advantages (and disadvantages) for genetic study, and what have we learned from it? Where are the classic papers, the key bibli ographies, and how does one get stocks of wild type or mutant strains? Lists giving the symbolism and descriptions for selected mutants that have been retained and are thus available for future studies are provided whenever possible. Genetic and cytological maps, mitotic karyotypes, and haploid DNA values are also included when available. Volume 4 deals with certain vertebrate species that have been studied in considerable detail from the standpoint of genetics or molecular cytogenetics. Such data are available for only a relatively few vertebrates.




The Coat Colors of Mice


Book Description

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.

Animal Science Reviews 2010 provides scientists and students in animal science with timely analysis on key topics in current research. Originally published online in CAB Reviews, this volume makes available in printed form the reviews in animal science published during 2010.




The Genetics of Cattle, 2nd Edition


Book Description

Since the time of domestication more than 10,000 years ago, cattle have played an increasingly crucial role in the development of human civilizations. Progress has been quite remarkable since the turn of the century; the sequencing of the bovine genome in 2009 launched new avenues for furthering our understanding of theoretical and practical aspects of cattle genetics. Covering a vast array of questions, this book reviews major topics from molecular and developmental genetics, disease resistance and immunogenetics to genetic improvement of dairy and beef breeds, addressing all current problems in the field. This second edition includes a new team of authors and completely new chapters on the genetics of fat production, nutrition, feed intake and efficiency, growth and body composition. Fully updated throughout, it provides a valuable resource on cattle genetics for researchers, breeders, veterinarians and postgraduate students.
