Abstract

Sequence variation was detected by polymerase chain reaction (PCR) and direct sequencing of a 295-nucleotide region of the mitochondrial cytochrome b gene of Arctic charr (Salvelinus alpinus), Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) sampled around Iceland. Four haplotypes were found within Atlantic salmon, no variation was found within Arctic charr or brown trout. Synonymous substitution rates among the species were according to a molecular clock. There was a significant transition/transversion bias but apparent transitional bias among purines and pyrimidines was not significant, given permissible mutations which would not alter the amino acid sequence. The amino acid sequences were identical among the species where intraspecific variation did not exist.
