The nucleotide sequence variation of mitochondria1 DNA were investigated by eight restriction endonucleases from two oyster species, Crassostrea gigas collected from two localities of South Korea and one locality of Japan and C. nippona collected from one locality of South Korea. The total mtDNA size in the oyster, C. gigas, from the three localities was approximately 18 kb and that in C. nippona was 22 kb. The restriction fragment patterns of mtDNA in C. gigas from the three localities by BamHI, BgII, and XhoI digestions were identical to one another. The degree of mtDNA sequence divergence of C. gigas between the two localities in Korea was 2% and that between Korean and Japanese C. gigas was 5%. The amount of sequence divergence between the two species of oysters was 42%.
