摘要

Polymorphic nucleotide sites were found in about 500 bp sequence from the 5' end of the control region of the mitochondrial (mt) DNA of chum salmon (Oncorhynchus keta) (Sato et al. 2001). The observed nucleotide sequence variation has so far defined 30 mtDNA haplotypes of three genealogical groups (clade A, B and C) in more than 2,100 individuals representing 48 populations from Japan, Korea, Russia, and North America including Alaska, British Columbia and Washington (Sato et al. in press). The observed haplotypes were mostly associated with geographic regions, in that clade A and Crnhaplotypes characterized Asian populations and clade B haplotypes distinguished North American populations (Fig. 1).
