토종닭과 실용계에서 TYR 및 MC1R 유전자의 변이 분석

다국어 초록 (Multilingual Abstract)

The commercial Korean native chickens (WR_CC) was developed by crossing a few native chicken breeds in Korea. In order to investigate the breed identification markers, SNPs from TYR gene and MC1R gene, which are associated with skin and feather colors respectively, were initially identified. In case of 3 identified SNPs in the TYR gene, yellow shank color was identified in Loss, Harvard, AA, RIR and CC, which have the fixed SNPs in most of the animals. On the other hand, SNP variations were observed in KNC_RB, C_B, WR_CC and HH_CC, which have the black, yellow and mixed color with black and yellow shank colors. Also, the investigation of 3 SNPs in the MC1R gene indicated that there were associations between shank and feather colors in RIR, SF, KNC_B, C_B and RIR. However, these results are not consistent among breeds. These SNP type inconsistencies within breeds suggested that the selection was performed based on the phenotypes, which is not include the genotype information. Thus, selection based on genetic information is required in the future.
