Electron microscope examinations of primary oocytes of gynogenetic triploid ginbuna (<I>Caras sius auratus langsdorfii</I>) and diploid gengoroubuna (<I>Carassius auratus cuvieri</I>) were carried out. Typical synaptonemal complexes were observed in both subspecies. In addition, clear differences in PGM-A electrophoretic patterns between a female parent ginbuna and her offspring were detected . It was concluded that synapsis and recombination occur between at least some homologous chromosomes in triploid ginbuna.
