Mitochondrial DNA Variation in Goldfish Carassius auratus gibelio from Far Eastern Water Reservoirs

MtDNA variation of goldfish samples from several reservoirs of Southern Primorye was examined by RFLP analysis. High mtDNA polymorphism was found in the river populations but not in the lake ones. Considerable among-haplotype divergence was found within samples, which suggests periodic gene exchange between populations having long histories of independent evolution. The absence of substantial differences between clusters of mtDNA haplotypes indicates recurrent transfer from bisexual to gynogenetic reproduction mode and vice versa.
