This Archive includes the best of the Genetics-related articles featured on Working Dogs Cyberzine since 1996.
Evangelizing Canine Genetic Diversity by Hellmuth Wachtel "Excessive elite breeding" combines only the very best, but also reduces the genetic pool, leading to a rapid exhaustion of the genetic improvement margin. ( Read More...)
Eight Good Reasons Not to Breed Your Dog Is your dog so cute you wish you could fill the world with creatures just like her? Many owners feel this way about their pets. Some even see breeding as a way to make some extra money, through the sale of the litter. ( Read More...)
Sheeptender Ann Garner reviews the classic history of the sheep tending dog. Time has not eradicated this resilient genetic foundation for the dogs that have retained and now daily utilize their remarkable herding instincts.
Genetics and the Border Collie is presented by the United States Border Collie Club. From basic genetics to complex genetic traits, the author addresses many of the genetic fundamentals that significantly affect the genotype and phenotype of the Border Collie.
Berkeley professors Melissa DeMille and C. Denise Wall present the Bare Bones Introduction to Genetics that introduces the major terms and concepts customarily used when discussing canine genetics.
Pat McNamara reports on the annual Cornell University Canine Genetics Conference held this year on October 4 and 5. Some of the world's leading geneticists and researchers presented information about current canine genetics studies and their results.
Canine Genetic Primer - A cadre of genetics professionals collaborated to create an excellent resource for basic canine genetics on the acmepet web site.
Why should I have my breeding dogs X-rayed? - The answer is broader than your one pup, or litter of pups, or even your own careful breeding program. The U.S. Border Collie Club explains why in their article Genetic Selection.
The Ring Sport Arena - Part I - Bob Dixon shares his expertise once again in his first installment of his Ring Sport Arena training series, "Introduction to Ring Sport." Learn about scoring, past champs, puppy training, and basic training theory and practice in this comprehensive primer.
Artificial Insemination - Veterinarian Mary C. Wakeman asks "Why AI?" There are several circumstances in which artificial insemination may be the best way of delivering semen to the bitch; and some circumstances when it surely isn't.
Prof. Sue Ann Bowling authors a detailed summary of Canine Color Genetics in which she discusses the genes that influence color and the types and lengths of coat. An excellent resource for learning how genes interact to control defined traits in the domestic canine.
Why is my dog sable? What will the puppies inherit from my brood bitch? What is DNA and why is it so important? If you've ever asked these questions, you know the answers aren't always simple. You now have the opportunity to learn the answers to these and other genetics questions from the convenience of your desktop. Breed enthusiasts worldwide have an extraordinary opportunity to participate in online Canine Genetics courses now offered by the Department of Animal Sciences at Cornell University. Three-week and six-week Canine Genetics Courses are now available at Cornell's Computer-Assisted Teaching Center. Classes fill rapidly, so register today to participate in this cutting-edge educational opportunity.
An extensive collection of links to helpful, informative online CANINE GENETICS RESOURCES is now available for everyone wanting to learn more about basic and advanced canine genetics, and how it will ultimately control the future of all sporting and working breeds.
Hellmuth Wachtel presents his SEVEN THESES OF CANINE DIVERSITY, written to encourage informed breeding, the retention of diversity in canine breed pools, and meeting the challenges of convincing breeders of the long-term benefits of incorporating diversity into their breeding programs.
Heritability is a statistic used to evaluate dogs and selectively breed them for a quantitative trait. Cornell geneticist John Pollack explains how HERITABILITY MEASURES THE VARIABILITY OF GENES that can control physical characteristics.
The Dogs in Canada web site features Siberian Husky breeder Jeffrey Bragg's commentary on the upsurge of genetic problems and his call for action in The Genetic Tide: Will It Leave Us High and Dry? We are seeing a steady increase in genetic defects. Bragg suggests that the answer lies in the well-proven science of population genetics.
The Canine Diversity web site features Genetic Testing: A Guide for Breeders by Mary Whiteley, PhD. Dr. Whiteley believes that we will soon have a test for most of the genetic diseases of dogs. In her article, she discusses genes, DNA, the genetic testing that is available to breeders today, and what the test results mean.
In their six-part series, authors Susan Thorpe-Vargas, John Cargill and Caroline Coile discuss how a single breeder's actions may have consequences that are far-reaching. Selective breeding practices may have created a genetic nightmare for many of our breeds today. In the first installment of that series, The Genetic Cul-de-Sac, the genetics task force addresses the origin of the domestic dog with an emphasis on the fundamentals of DNA and gene mutations, and their relationship to vigorous genetic diversity.
German Shepherd dog breeder Janice L. Bartmess reviews the history of DDR (East German) lines and the economic and political pressures that generated the divergence of the characteristic DDR lines from the remainder of the GSD genetic pool in Europe; and how that contributed to the importance of these bloodlines for the viability of the breed today.
Canadian Jeffrey Bragg details his arguments for achieving genetic soundness in his stimulating brief, Purebred Dog Breeds into the Twenty-First Century: Achieving Genetic Health for Our Dogs. Promoting a balanced, heterozygous breeding system, he focuses on the tremendous amount of work that is required of responsible breeders to preserve and advance canine working abilities. His model for genetic diversity demands a rational balance between working characteristics and the ideals of conformation.
Dealing effectively with any genetic problem requires an understanding of the relationship between the genes (genotype) and the phenotype. In his article, The Nature of Genetic Disease, Dr. John B. Armstrong sheds light on the differences between true genetic diseases and conformational diseases.
Geneticist and German Shepherd breed devotee Malcolm B. Willis, Ph.D. is the acclaimed author of the definitive work, The German Shepherd Dog: A Genetic History. Willis details the genetics of reproduction and behavior, with an in-depth study of hip dysplasia and other inheritable diseases of the breed.
