NOAA-NMFS-NWFSC TM-35: Chinook Status Review

Multidimensional scaling plot (MDS) of Cavall-Sforza and Edwards (1967) chord distances based on 29 allozyme loci between 193 composite samples of chinook salmon from populations extending from Alaska to California. The MDS clustering from these samples had a stress of 0.245, which represents a fair fit of distances between samples in the graph to the original genetics distances. Blue/green/purple symbols denote ocean-type populations and orange/red/yellow symbols denote stream-type populations, and gray symbols denote populations of intermediate type.
