Photographs of the Korean native chicken breeds. A: Korean wild chicken (W), B: Korean native chicken Red-line (KCR), C: Korean native chicken Yellow-red line (KCRD), D: Korean native chicken Black line (Ogol; KCO). 

Genotype pattern of FM PCR (MC1R) diagnostic test products. All chickens with W and Black type phenotype carry the FM allele while all chickens with Red and Yellow-red type phenotype do not carry the FM allele. KCR: Korean native chicken red, KCRD: Korean native chicken red-yellow (deep red), KCO : Korean chicken Ogol (Black-line). 

Analysis of polymorphic patterns in DNA poll of each group using URP-primer. Evolutionary relationships of taxa. The evolutionary history was inferred using the UPGMA method. The optimal tree with the sum of branch length = 1.09229610 is shown. The analysis involved 3 nucleotide sequences. Codon positions included were 1st+2nd+3rd+Noncoding. All positions containing gaps and missing data were eliminated. Evolutionary analyses were conducted in MEGA5. A: Agarose gel image of polymorphic pattern, B: Pairwise genetic distance, C: Dendrogram, M: 100bp DNA ladder, lane 1: W, lane 2: KCR, lane 3: KCRD, lane 4: KCO, KCR: Korean native chicken red, KCRD: Korean native chicken red-yellow (deep red), KCO: Korean chicken Ogol (Black-line).

Analysis of polymorphic patterns in DNA samples. A: RAPD profiles using URP primer between Korean chickens. B: The unweighted pair group method of analysis (UPGMA) dendrogram based on summarized data regarding differentiation among chickens. KCR: Korean native chicken red, KCRD: Korean native chicken red-yellow (deep red), KCO: Korean chicken Ogol (Black-line). 

The unweighted pair group method of analysis (UPGMA) dendrogram based on summarized data regarding differentiation among Korean chickens. KCR: Korean native chicken red, KCRD: Korean native chicken red-yellow (deep red), KCO: Korean chicken Ogol (Black-line). 

The UPGMA dendrogram based on summarized data regarding differentiation between Korean chickens and Korean wild chicken. W: Korean wild chickens, KCR: Korean native chicken red, KCRD: Korean native chicken red-yellow (deep red), KCO: Korean chicken Ogol (Black-line).
