Abstract

Abstract

The karyotypes of hybrid scallop(hybridizing cross the female Patinop ecteny essoensis with the Chlamys farreri) and their parents were studied and compared by colchine hy potonic air drying-Giemsa staining.Some cytogenetic specificities were detected.The karyotype of C.farreri was found to be 2n=38=6m+10sm+22st,while the karyotype of P.yessoensis was 2n=38=6m+10sm+16st+6t.The chromosome number of the hybrid is 2n=38,however,the karyotypes are quite different from the expectative types,much more number of telocentric chromosomes appear.Moreover,obvious polymorphism of karyotypes was examined in the hybrids izatims.
