The Future - DNA Testing for Labrador genetic problems

MMI Genomics' initial focus in the companion animal industries is the development of diagnostic assays that allow early detection for debilitating genetic disorders such as chronic hip dysplasia in Labrador and Retriever breed types....These tools will also be used in breeding programs to eliminate defective genes from the population and to certify the health status of individual animals prior to purchase.

It looks like they have two tests so far - DNA Identity (called Paw Print ) and Parentage (called GeneMatch Pedigree), both costing $55US
