Genotypic distribution of cultured KF blue mussels. Genotypic assessment of 19 individuals was done by amplification with the nuclear markers EFbis and Glu-5′. Hybrid scores were calculated by counting all amplified alleles belonging to Me. A hybrid score of 4 is representing pure Me background (0: pure Mt, 1: Mt-like hybrid, 2: intermediate hybrid, 3: Me-like hybrid, 4: pure Me).
