This study was conducted to evaluate the genetic distances and specific DNA makers by the randomly amplified polymorphic DNA (RAPD)-PCR method for the Korean native chickens(red plumage, red-line plumage, Ogol) and white leghorn. Genomic DNA was extracted from plumage from chickens after they were slaughtered. The extracted DNA was observed by nano-spectrometer. RAPD analysis was performed using 13 different primers. Statistical analysis was made for the estimation of the genetic distance among the chicken’s and the cluster tree was drawn by using MEGA 5.05 software. Genetic relations among them were determined by RAPD analysis. The polymorphic bands were observed 72% and the rest of 28% was monomorpic. The largest genetic distance (2.266) was found between the native chickens(red, red-line) and the ogol chickens by UPGMAP method and the closest distance was observed between the ogol in korean chickens as expected. The highest genetic distance between them was estimated 2.266 and in the dendrogram analysis, among I and II within cluster II, most of the ogol chickens were in IIB, indicating the expression of the ogol color could be due to original and the ancestral genetic crossing. Thus, this genetic distance can be useful as the differential genomic information in the normal(red plumage, red-line plumage) and ogol of korean native chickens.
