Claim:
A method for identifying a dog as likely not to be affected with progressive rod cone degeneration comprising: a) obtaining a biological sample comprising nucleic acids from the dog; and b) testing the biological sample comprising the nucleic acids for the presence of at least one prcd polymorphism present on a chromosome 9 homolog; wherein the at least one prcd polymorphism is A, or T as the reverse complement of A, wherein the A or the T are located at nucleotide position 7217488 of canine chromosome 9 in the May 2005 Canis familiaris whole genome shotgun assembly, and wherein the presence of the at least one prcd polymorphism on only one chromosome 9 homolog or the absence of the at least one prcd polymorphism in both chromosome 9 homologs identifies the dog as likely to be not affected with progressive rod cone degeneration.
