Population structure of the Antarctic toothfish, Dissostichus mawsoni from the Areas 58 and 88 in the Antarctic Ocean based on mitochondrial and microsatellite DNA markers
localities from the two main Subareas 88 and 58, based on a combined analysis of mitochondrial DNA (mtDNA ... ) cytochrome oxidase I (COI) sequences and four nuclear microsatellite loci. MtDNA revealed a very low level of ... of 5.8 to 6.7 within populations. Four of six populations showed a genetic signal of inbreeding ... suggest that the sampled 88 Subarea populations are likely to comprise a well-admixed single gene pool ...
