Canine Genetic Linkage Map


The canine linkage map is the principal tool for gaining unbiased genetic access to causal pathways underpinning diseases in the dog. Previously published maps have consisted of fewer than 500 markers. The linkage map presented here is comprehensive, and is based on pedigree resources with greater mapping power than the human CEPH.
