Introduction to Veterinary Genetics

• Broschiertes Buch

Produktbeschreibung

The concepts of veterinary genetics are crucial to understandingand controlling many diseases and disorders in animals. Theyare also crucial to enhancing animal production. Accessible andclearly presented, Introduction to Veterinary Genetics provides a succinct introduction to the aspects of geneticsrelevant to animal diseases and production. Now in its thirdedition, this is the only introductory level textbook on geneticsthat has been written specifically for veterinary and animalscience students.
Coverage includes: basic genetics, molecular biology, genomics,cytogenetics, immunogenetics, population genetics, quantitativegenetics, biotechnology, and the use of molecular tools in thecontrol of inherited disorders.

This book describes in detail how genetics is being applied toartificial selection in animal production. It also coversthe conservation of genetic diversity in both domesticated and wildanimals.

New for the Third Edition:

End-of-chapter summaries provide quick recaps.
Covers new topics: epigenetics, genomics andbioinformatics.
Thoroughly revised according to recent advances ingenetics.
Introduction to Veterinary Genetics is still the onlyintroductory genetics textbook for students of veterinary andanimal science and will continue to be an indispensable referencetool for veterinary students and practitioners alike.

Autorenporträt

Frank Nicholas is Emeritus Professor of Animal Genetics in the Faculty of Veterinary Science at the University of Sydney.  He has edited and co-authored several books about genetics and one about Charles Darwin, and he created and maintains Online Mendelian Inheritance of Animals (OMIA; omia.angis.org.au), a comparative knowledge-base of genetic disorders and other familial traits in non-laboratory animals.
