Random amplified polymorphic DNA (RAPD) analysis has been used widely in plant and fungi for identification of markers linked to genetic traits and mapping, but its use is limited to identification of intra- and inter-species difference in domestic mammals. We report here identification of a RAPD-derived marker linked to progressive rod-cone degeneration (prcd), an inherited autosomal recessive retinal disease of dogs. A total of 400 standard 10-mer primers were used for amplification by use of DNA samples from normal (+/+) and affected (prcd/prcd) dogs. A single primer was identified which amplified a 1.5-kb DNA fragment only from normal dogs. PCR …
