Biogeographic Evidence for Selection on Mitochondrial DNA in North Pacific
Three major mitochondrial DNA (mtDNA) haplogroups were identified in 5 data sets for North Pacific and Bering Sea walleye pollock. The common haplogroup A showed mirror-image clines on both sides of the North Pacific with high fre-quencies in southern areas (PA. 0.84) and low frequencies in the Beri...
