Hi Guys I am re-sending this because I got an "ecartis" (bounce) so if you have already seen it, I apologize. Paula according to Dr. Jerold Bell, Tufts Univ, Geneticist, Vet, Breeder and Exhibitor, it IS polygenic Here is a quote from one of his articles from the AKC. *"Degenerative myelopathy is considered a complexly (polygenic) inherited disease. An autosomal recessive susceptibility gene has been identified that is homozygous (two abnormal copies) in all DM affected dogs. However, a large proportion of individuals in these breeds are homozygous for this gene and do not become affected. They are considered ?at risk?, but not genetically affected."* * * *Here is the link to his full article. It is a PDF, so scroll down to the 3rd set of pages,* *the DM subject begins there.* *http://clubs.akc.org/NBC/Bell%20Handout%20-%20NBC.pdf<http://www.facebook.com/l.php?u=http%3A%2F%2Fclubs.akc.org%2FNBC%2FBell%2520Handout%2520-%2520NBC.pdf&h=ZAQErUuD5AQFcaXdYc6pwJpJkQeXB8JEPAcDmhk--Saoxjw&enc=AZOuTWrEH42E_FWRD2_Z9HLQPfKMo4PdhyystKij6j5bB84I_DXO7Lx5UpirDQoRKZBu2MsiF-c2xSZcQKE1atPlfm94Ma9BhFM2YYD0oEJYXg> * * * Kathy * * * * * * *"Victory...*Vires et honestas" ============================================================================ POST is Copyrighted 2011.
