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 injection of 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 2n=38.The karyotype of Solen grandis is 26 m+6 sm+2 st+4 t,NF=70,of Saxidomus purpuratus is 32 m+2 sm+4 st/t,NF=72,of Mactra chinensis is 20 m+16 sm+2 st/t,NF=74. Satellite and sex chromosome were not found among the chromosomes of three species.
