We examined allozyme variation in the parents and offspring of 41 crossings of coho salmonOncorhynchus kisutch.Mendelian inheritance previously unreported for Pacific salmon was confirmed at 11 loci:sAAT-4*, sAH*, ALAT*, EST-1*, βGALA*, GAPDH-2*, GPI-B2*, sMDH-A1,2*, PEPA*, PEPC*, andPNP-1*.Independent assortment was found for the following locus pairs:ADA-1*andβGALA*, ALAT*andβGALA*, ALAT*andEST-1*, EST-1*andβGALA*, EST-1*andPEPC*, GAPDH-2*andPNP-1*, βGALA*andGPI-B2*, βGALA*andsMDH-A1,2*, andβGALA*andPEPC*.
