| Abstract: | The karyotypes of three species of marine Veneroida molluscs, Solen grandis Dunker,Saxidomus purpuratus Sowerby and Mactra chinensis Philippi were studied by using the adult gill tissues. The chromosomes were prepared through injecting phytohemagglutinin (PHA) and colchicine, hypotonic treatment, chopping air-dry, and squashing technology. The results show that the diploid chromosome numbers of the three Veneroida species are the same as 2 n = 38. The karyotype of Solen grandis is 26m 6sm 2st 4t, NF = 70, the karyotype of Saxidomus purpuratus is 32m 2sm 4st/t, NF = 72, and the karyotype of Mactra chinensis is 20m 16sm 2st/t, NF = 74. Satellite and sex chromosome were not found among the chromosomes of three species. |
