The karyotypes of Meretrix lusoria and M. petechialis in the family Veneridae in Korea were studied in order to analyse their genetic relationships. The 2 species showed a diploid chromosome number of 2n=38, with 5 metacentric, 10 submetacentric, 2 subtelocentric, and 2 telocentric chromosome pairs for Meretrix lusoria, and 5 metacentric, 9 submetacentric, 3 subtelocentric, and 2 telocentric for M. petechialis. The karyotypes of these 2 species are clearly different in the same genus.
