In order to identify the genetic compositions of the grey brown Korean Native Chicken(gKNC), this study was compared to other 6 strains of birds by DN.A fingerprintings. The gKNC was nearly fixed as genetic strain in homozygotic ratio and band sharing within grain of DNA bands. Band sharing of inter-strain of the gKNC with yellow brown Native Chicken was showed high similarity(0.76), and considerable band sharing of 0.325 with commercial broiler was suggested possibility of improvement as meat type. Through pedigree analysis of DNA bands, paternal DNA bands of gKNC were inherited significantly higher than maternal to progeny. Strain specific band, genetic composition of meat type, and powerful inheritance of sire would be important tools to improve the grey brown Korean Native Chicken in a future.
