The haemoglobin and four different isozymes were analysed in erythrocytes of silver crucian carp, Carassius auratus gibelio and red common carp, Cyprinus carpio red variety, and their hybrid, the multiple tetraploid allogynogenetic crucian carp, C. auratus, using polyacrylamide gradient gel electrophoresis technique. Some loci (Hb, EST, SOD) in multiple tetraploid allogynogenetic crucian carp expressed not only the maternal but also the paternal genes. Some bands appeared which is not original in silver crucian carp, and some original bands in silver crucian carp were repressed. It is thus indicated that the multiple tetraploid allogynogenetic crucian carp exhibited features of a hybrid, and that isozyme gene expressions of the allogynogenetic crucian carp should be much closer to the silver crucian carp from the analyses of phenotypes of four different isozymes.
