In order to breed the Korean native dog, sapsaree, which exist as a single population in KyungPook province, we are going to use DNAfingerprinting as a tool for studying the pedigree. In this experiment, 4 kinds of DNA probes, Exon 8, Intron B, M13, and pV47-2 were analysed by means of conventional Southern hybridization with Sapsaree genomic DNAs digested with restriction enzymes for their usefulness as probe. On the basis of their autoradiographic band patterns and resolution, pV47-2 was determined to be the best probe for studing the pedigree of sapsaree.
