Origins of the Domestic Dog and the Rich Potential for Gene Mapping

Abstract EN

The unique breeding structure of the domestic dog makes canine genetics a useful tool to further the understanding of inherited diseases and gene function.

Answers to the questions of when and where the dog was domesticated from the wolf are uncertain, but how the modern diversity of dog breeds was developed is documented.

Breed development has resulted in many genetically isolated populations which are segregating for different alleles for disease and morphological and behavioral traits.

Many genetic tools are available for dog research allowing investigation into the genetic basis of these phenotypes.

Research into causes of diseases in dogs is relevant to humans and other species; comparative genomics is being used to transfer genetic information to them, including some studies on morphological and behavioral phenotypes.

Because of the unique breed structure and well-maintained pedigrees, dogs represent a model organism containing a wealth of genetic information.
