title: Toward a framework linkage map of the canine genome.
abstract: Selective breeding to maintain specific physical and behavioral traits has made the modern dog one of the most physically diverse species on earth. One unfortunate consequence of the common breeding practices used to develop lines of dogs with the desired traits is amplification and propagation of genetic diseases within distinct breeds. To map disease loci we have constructed a first-generation framework map of the canine genome. We developed large numbers of highly polymorphic markers, constructed a panel of canine-rodent hybrid cell lines, and assigned those markers to chromosome groups using the hybrid cell lines. Finally, we determined the order and spacing of markers on individual canine chromosomes by linkage analysis using a reference panel of 17 outbred pedigrees. This article describes approaches and strategies to accomplish these goals.
