In this study, 16 sets of primers were used to amplify contiguous, overlapping segments of the complete mitochondrial DNA (mtDNA) of the hybridized fish (Oncorhynchus mykiss female x Atlantic salmon male) in order to characterize and compare their mitochondrial genomes. The total length of the mitochondrial genome is 16,658 bp and deposited in the GenBank with accession numbers KP218514. The organization of the mitochondrial genomes contained 37 genes (13 protein-coding genes, two ribosomal RNA, and 22 transfer RNAs) and a major non-coding control region which was similar to those reported mitochondrial genomes. Most genes were encoded on the H-strand, except for the ND6 and eight tRNA genes, encoding on the L-strand. Similarity and divergence analysis also showed that hybrid offspring were genetically closer to mother parent than father parent. These results indicate that, despite hybridization, the mitochondrial genomes of these hybrids remain maternally inherited.
