Evidence for recombination of mitochondrial DNA in triploid crucian carp.

ABSTRACT: In this study, we report the complete mitochondrial DNA (mtDNA) sequences of the allotetraploid and triploid crucian carp and compare the complete mtDNA sequences between the triploid crucian carp and its female parent Japanese crucian carp and between the triploid crucian carp and its male parent allotetraploid. Our results indicate that the complete mtDNA nucleotide identity (98%) between the triploid crucian carp and its male parent allotetraploid was higher than that (93%) between the triploid crucian carp and its female parent Japanese crucian carp. Moreover, the presence of a pattern of identity and difference at synonymous sites of mitochondrial genomes between the triploid crucian carp and its parents provides direct evidence that triploid crucian carp possessed the recombination m
