Genetic diversity among different clones of the gynogenetic silver cruciancarp, Carassius auratus gibelio, revealed by transferrin and isozyme markers

Genetic diversity among four clones (A, D, E, F) of gynogenetic silver cruc ian carp was studied using transferrin and isozymes in the blood as markers . Of the five proteins investigated, three (transferrin, esterase and super oxide dismutase) indicated polymorphism and eight polymorphic loci were det ected. These loci were probably encoded by codominant alleles and their inh eritance patterns were analyzed. Intraclonal homogeneity and interclonal he terogeneity were observed in these clones, which allowed us to infer the cl onal nature and evolutionary relationship between them. Clonal diversity in this population of silver crucian carp in China was also compared with dat a reported from gynogenetic crucian carp in Germany.
