[Mitochondrial DNA variation in diploid and triploid forms of silver crucian carp Carassius auratus gibelio].
Variation of two mtDNA fragments amplified in polymerase chain reaction was compared by the RFLP method in a population of the sympatric bisexual (diploid) and gynogenetic (triploid) forms of silver crucian carp. The mtDNA haplotypes of all individuals differed in at least 2.5% of nucleotide substitutions and fall into two phylogroups. All gynogenetic individuals have haplotypes of a single phylogroup, whereas haplotypes of diploid fish belonged to both mtDNA phylogroups. This testifies to a possibility of transformation of gynogenetic individuals into a bisexual form, whereas the reverse process is either extremely rare or impossible.
