  1. Cnn = Chondrostoma nasus nasus; Ctt = Chondrostoma toxostoma toxostoma; Hy = Hybrids; HR = Highly regulated river part; LR = Less regulated river part. * For CN analysis we added one allopatric Ctt population (Doubs N=15) and three Cnn populations (Allier N = 15, Flet N = 15, Usses N = 15). See text for details of the identification of C. n. borysthenicum in Dniester river.
